Abstract

In this paper, we establish bounds of the Rankin-Selberg $L$-function for $SL(2)$ using the supnorm of the Eisenstein series and a purely representation theoretic index over the real group. Consequently, we obtain a subconvexity bound $L(\frac{1}{2}+ it, f_1 \times f_2) \leq C (1+ |t|)^{\frac{5}{6}+ε}$ for two Maass cusp forms of $SL(2, \mathbb Z)$.

A local relative trace formula for F*\SL(2,F)

In this note, we derive explicitly the local relative trace formula for the symmetric space F*\SL(2,F) at the level of Lie algebras, where F is a p-adic field of residue characteristic greater than two and F* is the set of invertible elements in F. This is perhaps one of the simplest non-trivial analogs of the trace formula, and also a motivating example for the author's work (in preparation) on the relative trace formula.

Remarks on the shuffle elements of Iwahori--Hecke algebras

Let $H_n(q)$ be the generic Iwahori--Hecke algebra associated to the symmetric group $\mathfrak{S}_n$ of degree $n$ and let $\mathscr{Y}_{n,i}$ be the sum of standard basis of $H_n(q)$ with Coxeter length $i$ for $1\leq i\leq \binom{n}{2}$. We show that $\mathscr{Y}_{n,1}$ and $\mathscr{Y}_{n,2}$ are noncommutative whenever $n\geq 4$, which disproves Doikou's Conjecture on the commutativity of the shuffle elements of $H_n(q)$ in (Nuclear Physics B 1029 (2026): 117532). We also show that the matrix of the operator of the left multiplication by $\mathscr{Y}_{n,i}$ in $H_n(q)$ is $q$-symmetric for all $i$.

Monoidal categorification on open Richardson varieties

Let $G$ be a simply connected complex semisimple group of finite simply-laced type, and let $v\leq w$ be Weyl group elements. We construct a monoidal categorification of open Richardson varieties in this setting. The construction realizes the cluster variables of Ménard's seed by real simple modules in the quiver Hecke category $\mathscr C_{w,v}$, by comparing their truncated Lusztig parameters with the $Δ$-vectors at every step of Ménard's mutation algorithm. Every mutation in a retained direction is realized inside $\mathscr C_{w,v}$. After localizing at the determinantial modules $M(w\varpi_i,v\varpi_i)$, the resulting category is a monoidal categorification of the coordinate ring of the open Richardson variety $\mathring{\mathcal B}_{v,w}$. In particular, cluster monomials without negative frozen exponents are represented by real simple modules in $\mathscr C_{w,v}$; arbitrary frozen Laurent factors are realized in its localization.
