REU projects

This RTG grant also has financial support for undergraduates involved in research (REU activities). These funds are administered through the departmental REU programs. Please CLICK HERE for more information.

Research Training Seminar

Early graduate students (as well as advanced undergraduates), are encouraged to participate in annual RTG training seminars. These annual seminars will have students work through research material in a collaborative setting, leading towards producing research in or a new exposition of a research topic.

Current topic: (run by Christopher Hacon) This seminar is mainly targeted at beginning graduate students with an interest in algebraic geometry. We will follow Lazarsfeld's book Positivity in Algebraic Geometry I and II and aim to identify related open problems and conjectures in complex projective geometry. The ideal prerequisites for this course is familiarity with Hartshorne or a similar introductory text in algebraic geometry.

RTG Travel Funding

The RTG grant has limited funds available for participants (at both the undergraduate and graduate levels) to travel to conferences and other events, including those focused on building connections and mentorship networks.

2019-2020 academic year rules

The mathematics department has limited funding that graduate and undergraduate students can use to go to conferences, workshops, summer schools, etc. in any area of pure math covered by the RTG grant. Applicants must be U.S. citizens or permanent residents. Applications are accepted on a rolling basis and will be reviewed on the 1st of every month. Applications will be reviewed by a committee consisting of two co-PIs of the RTG grant (currently Priyam Patel and Stefan Patrikis).

Applicants should submit the following materials via email to BOTH of the committee members:
  • a letter justifying the travel, including a rough budget with explanations,
  • a recommendation letter from a faculty member (an informal email to the two committee members would sufce), and
  • any relevant supplemental material (conference invitation etc.).
The committee will make a decision within the frst week of every month and the applicant (as well as the letter writing faculty) will be notifed via email regarding the results, including the amount of the award if successful. Priorities for funding will be given to applicants who are invited to give a presentation of original results and who have not received support in the past. Due to limited funding, each applicant is limited to $500 per year from this source

Current RTG postdocs:
  • Leo Herr (2019--2022): Leo's work concerns applications of Log Geometry in calculating Gromov-Witten Invariants. This extends the breadth to which these invariants may be applied to mildly singular spaces. Leo will work most directly with Y. P. Lee.
  • Elizabeth Field (2020--2023): Elizabeth's research lies in geometric group theory and low-dimensional topology. She is particularly interested in hyperbolic groups and spaces, boundaries of groups and spaces, and mapping class groups. She will be working with Mladen Bestvina, Ken Bromberg, Priyam Patel, and the rest of the GGT group at Utah.
  • Alicia Lamarche (2020--2023): Alicia is interested in algebraic and arithmetic geometry, and her recent work has focused on methods of extracting arithmetic information from the derived category of coherent sheaves of a variety. She plans on working with Karl Schwede, Aaron Bertram, and the rest of the AG community at Utah.
  • Joshua Pollitz (2019--2022): Josh' primary research interests are studying and applying homological algebra in the context of commutative algebra and its related areas. While an RTG postdoc he plans on working with Srikanth Iyengar and other faculty members in the commutative algebra community at Utah.
  • Peter Wear (2020--2023): Peter studies arithmetic geometry. His focus is on the non-archimedean geometry of perfectoid spaces and related objects. He will be working primarily with Sean Howe.

  • Aaron Bertram: Aaron works within algebraic geometry; specifically on questions about moduli spaces related to mirror symmetry. Current interests include stable maps and Gromov-Witten theory, derived categories and Bridgeland stability conditions, and the relationship between classical Riemann surface theory and tropical curves (i.e., metric graphs).
  • Mladen Bestvina: Mladen studies geometric group theory. Of particular interest is the geometry of Outer Space and other spaces associated to Out(F_n), as well as mapping class groups, Teichm\uller space and curve complexes. Other interests include: asymptotic dimension, bounded cohomology, limit groups.
  • Ken Bromberg: Ken works on hyperbolic geometry and deformation spaces of Kleinian groups. He is particularly interested in the "bumping" phenomena leading to non-local connectivity of deformation spaces. Other interests: geometric group theory, actions on quasi-trees, asymptotic dimension.
  • Jon Chaika: Jon works on ergodic theory, interval exchange transformations and flows on flat surfaces. He is particularly interested in diophantine approximation and also non-unique ergodicity. His other interests include properties of and actions on the parameterizing space of interval exchanges and flat surfaces, diophantine approximation in abstract settings and isomorphism problems.
  • Tommaso de Fernex: Tommaso works in algebraic geometry, with focus on problems in birational geometry of higher dimensional varieties and singularity theory. Of particular interest are topics related to rationality, Fano varieties, log canonical thresholds and multiplier ideals, spaces of arcs, and non-archimedean geometry.
  • Christopher Hacon: Christopher's research is focused on the birational geometry of varieties and especially on questions related to the minimal model program, both in characteristic 0 and in positive characteristics. In particular he studies global questions such as the geometry of pluricanonical maps of projective varieties and the geometry of irregular varieties, as well as local questions regarding singularities of quasi-projective varieties and their invariants such as the log canonical thresholds and minimal log discrepancies.
  • Sean Howe: Sean works at the crossroads of algebraic geometry, number theory, and representation theory. His current research focuses on: 1) p-adic automorphic forms and their role in the p-adic Langlands program, and 2) arithmetic and motivic statistics. Most of his work is on problems that connect representation theoretic structures to the geometry and topology of moduli spaces.
  • Srikanth Iyengar: Srikanth is interested in commutative algebra and its manifestations in other fields, especially the representation theory of finite groups, and dimensional algebras. Some of the topics he likes to think about are free resolutions (finite and infinite), structure of morphisms, Hochschild and Andre-Quillen (co)homology, and various triangulated categories linked to commutative rings.

Current work focuses on Galois representations: deformation theory, monodromy groups and independence-of-l questions, and their motivic origin (the Fontaine-Mazur conjecture).
  • Gordan Savin: Works in representation theory and number theory, in particular, representations of p-adic groups and algebraic structures related to exceptional reductive groups. Current work includes research on the Gan-Gross-Prasad restriction program, and exceptional theta correspondences.
  • Karl Schwede: Karl works on the border between algebraic geometry and commutative algebra. He is especially interested in singularities, their relation to the minimal model program and characteristic $p$ methods such as Frobenius splittings and tight closure theory. More recently, he has been working to develop a theory of singularities in mixed characteristic.
  • Anurag Singh: Anurag studies commutative algebra, specifically questions related to local cohomology, tight closure theory, determinantal ideals, and invariant theory. Current projects include the study of local cohomology and differential operators in the integral setting.
  • Peter Trapa: Peter studies representations of reductive Lie groups over local fields. Recent work focuses on relating the underlying geometry of the Local Langlands Conjectures (for example, singularities of spaces of Langlands parameters) to questions of harmonic analysis on reductive groups (for example, the classification of unitary representations).
