Gus Schrader

I'm a graduate student in the math department at UC Berkeley. My advisor is Nicolai Reshetikhin. At the moment, my research is focused on quantum groups, quantum character varieties, cluster algebras and integrable systems. I'm also interested in applications of theta functions in mathematical physics and algebraic geometry.

Here are some links to my papers on the arXiv:

  • A cluster realization of the R-matrix from quantum character varieties (joint with Alexander Shapiro.)

  • Quantum groups, quantum tori, and the Grothendieck-Springer resolution (joint with Alexander Shapiro.)

  • Dual pairs of quantum moment maps and doubles of Hopf algebras (joint with Alexander Shapiro.)

  • Algebraic integrability of the classical XXZ spin chain with reflecting boundary conditions

  • Integrable systems from the classical reflection equation

  • The Universal Kummer Threefold (joint with Qingchun Ren, Steven Sam and Bernd Sturmfels.)

  • XXZ Scalar Products, Miwa Variables and Discrete KP (joint with Omar Foda.)
