Dear all, (cc: Sin-Myung Lee) We are pleased to announce the relaunch of the CART seminar series! This event is also a part of the HCMC Algebra seminar (http://newton.kias.re.kr/~chlee/cas/). Our first CART seminar in this semster is scheduled for September 5 (Thursday) from 10:30 to 11:30 (Korea time). Professor Brendon Rhoades from UCSD will be delivering a presentation on "Harmonics and graded Ehrhart theory." (https://sites.google.com/view/cart-kias/) You can join the seminar via the following: Zoom link: https://us06web.zoom.us/j/85468134798?pwd=b54rZI2qw5p31ZR9YXfbesPriWNAo6.1 Meeting ID: 854 6813 4798 Passcode: 692005 To stay updated on future events, please subscribe to our mailing list via https://snurep.crystalline.site/postorius/lists/cart-seminar.snurep.crystal….

Seminar announcement (Hideya Watanabe, June 21 (Fri), 11:00AM)

Dear all, The upcoming CART seminar is scheduled on June 21st (Friday), 10:00 - 11:00 (Korea time). Speaker: Hideya Watanabe (Rikkyo University) Title: Combinatorial $K$-matrices arising from affine quantum symmetric pairs of type $A$ Abstract: A combinatorial $R$-matrix is a solution to the combinatorial Yang-Baxter equation, which plays a vital role in discrete dynamical systems such as box-ball systems. It has been known that the theory of crystal bases arising from quantum groups provides us with a framework to construct combinatorial $R$-matrices systematically. In a dynamical system which has a boundary, the role of the combinatorial Yang-Baxter equation is replaced by the combinatorial reflection equation, whose solutions are called combinatorial $K$-matrices. In this talk, based on a joint work with Hiroto Kusano and Masato Okado, I will explain how to construct combinatorial $K$-matrices systematically by means of the theory of crystal bases arising from affine quantum symmetric pairs of type $A$. You can join the seminar via the following Zoom link: https://us06web.zoom.us/j/84037748851?pwd=MaC7wkX5TTLAQAGRr7L4uVgfs9Vaqd.1 Meeting ID: 840 3774 8851 Passcode: 640815 Please feel free to forward this to anyone who might be interested.

Dear CART seminar subscribers, This is a gentle reminder of the CART seminar by Oleksandr Tsymbaliuk (Purdue University), on 19;30 - 20:30 tomorrow (in Korea, UTC+9). Hope to see you at the seminar!

Speaker: Oleksandr Tsymbaliuk (Purdue University) Title: Lyndon words and fused currents in shuffle algebra Abstract: Classical q-shuffle algebras provide combinatorial models for the positive half U_q(n) of a finite quantum group. We define a loop version of this construction, yielding a combinatorial model for the positive half U_q(Ln) of a quantum loop group. In particular, we construct a PBW basis of U_q(Ln) indexed by standard Lyndon words, generalizing the work of Lalonde-Ram, Leclerc and Rosso in the U_q(n) case. We also connect this to Enriquez' degeneration A of the elliptic algebras of Feigin-Odesskii, proving a conjecture that describes the image of the embedding U_q(Ln) -> A in terms of pole and wheel conditions. The talk shall conclude with the shuffle interpretations of fused currents proposed by Ding-Khoroshkin. This is based on joint works with Andrei Negut.
