Tianyi Yu

    I am a second-year Ph.D. in the math department at the University of California, San Diego. My advisor is Brendon Rhoades. My research is about algebraic combinatorics. Currently, I am interested in the Lascoux polynomials, which can be viewed as K-theoretic analogues of key polynomials. Previously, I obtained bachelor's degrees in Mathematics and Computer Science at the University of California, San Diego. My email address is tiy059 (at) ucsd.edu.
