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 Priyam Patel) During the fall semester we will read a classical paper of Bill Thurston’s entitled “Entropy in dimension one” which can be found here: https://arxiv.org/pdf/1402.2008.pdf. Roughly, the paper studies which positive real numbers arise as the topological entropy of a postcritically finite self-map of the unit interval. We will also focus on another theorem of the paper that determines which positive real numbers arise as the topological entropy for an ergodic train track representative of an outer automorphism of a free group. 
Students will be asked to read the paper and take turns presenting various aspects of it throughout the semester. The plan for the spring semester is to try to fill in some of the missing details in the paper and perhaps write an expository paper on one or more of the theorems discussed.

    Current RTG postdocs:
  • Daniel Bragg (2022--2025): Daniel's research is in algebraic and arithmetic geometry. Daniel is interested in K3 surfaces, derived categories, and Brauer groups, particularly in mixed and positive characteristic. He plans to talk with Aaron Bertram, Christopher Hacon and Karl Schwede.
  • Devlin Mallory (2021--2024): Devlin is interested in singularities of rings from the point of view of algebraic geometry and commutative algebra. Most recently, he is working on connections between differential operators of singular rings and the global positivity properties of projective varieties. He plans to work with Anurag Singh and Tommaso de Fernex, as well as the broader AG and CA 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.

    • 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.

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.
    • Y.P. Lee: Works on algebraic geometry and mathematical physics, with emphasis on Gromov-Witten theory and its relations with and applications to algebraic cobordism, birational geometry, K-theory, integrable systems, mirror symmetry, moduli of curves, and variation of Hodge structures.
    • Dragan Milicic: Works in representation theory of Lie groups, specifically in analytic, algebraic and geometric aspects of representation theory of real reductive Lie groups. His current interests are focused on applications of the theory of holonomic D-modules to the study of categories of Harish-Chandra modules and related categories of representations.
    • Priyam Patel: Priyam works in low-dimensional topology and geometry and geometric group theory. She is particularly interested in hyperbolic manifolds and their finite degree covering spaces, arc and curve complexes associated to hyperbolic surfaces, Teichmuller theory, right-angled Artin groups, and cube complexes. More recently, she has been studying surfaces of infinite type and their (big) mapping class groups.
    • 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).
    • Kurt Vinhage: Kurt works in classification and rigidity properties of dynamical systems and group actions. He works in both the hyperbolic setting, where irreducible group actions are conjectured to be smoothly equivalent to ones of algebraic origin, and the parabolic setting, where the natural notion of equivalence for classification is a restricted measurable orbit-equivalence.
    • Kevin Wortman: Kevin works in geometric group theory, particularly on lattices in locally compact groups and their corresponding actions on nonpositively curved complexes and spaces, as well as some of their naturally occurring subspaces. Of particular interest are finiteness properties of groups and group cohomology.
