Weight posets associated with gradings of simple Lie algebras, Weyl groups, and arrangements of hyperplanes
Dmitri I. Panyushev
The set of weights of a finite-dimensional representation of a reductive Lie algebra has a natural poset structure ("weight poset"). Studying certain combinatorial problems related…
Derived categories of cyclic covers and their branch divisors
Alexander Kuznetsov, Alexander Perry
Given a variety with a rectangular Lefschetz decomposition of its derived category, we consider a degree cyclic cover ramified over a divisor . We co…
Refined blowups
D. Kaledin, A. Kuznetsov
Categorical resolution of singularities has been constructed in arXiv:1212.6170. It proceeds by alternating two steps of seemingly different nature. We show how to use the formalis…
Determinantal identities for flagged Schur and Schubert polynomials
Grigory Merzon, Evgeny Smirnov
We prove new determinantal identities for a family of flagged Schur polynomials. As a corollary of these identities we obtain determinantal expressions of Schubert polynomials for…
The matrix model for hypergeometric Hurwitz numbers
Jan Ambjorn, Leonid Chekhov
We present the multi-matrix models that are the generating functions for branched covers of the complex projective line ramified over fixed points , , (genera…
Classification of simple Lie superalgebras in characteristic
Sofiane Bouarroudj, Alexei Lebedev, Dimitry Leites +1
All results concern characteristic 2. Two procedures that to every simple Lie algebra assign simple Lie superalgebras, most of the latter new, are offered. We prove that every simp…
Lax operator algebras and gradings on semi-simple Lie algebras
Oleg K. Sheinman
A Lax operator algebra is constructed for an arbitrary semi-simple Lie algebra over equipped with a -grading, and arbitrary compact Riemann surface with mark…
Bilinear equations on Painleve tau functions from CFT
M. A. Bershtein, A. I. Shchechkin
In 2012 Gamayun, Iorgov, Lisovyy conjectured an explicit expression for the Painlevé VI ~function in terms of the Liouville conformal blocks with central charge . We prove…
An Overview of Transience Bounds in Max-Plus Algebra
Thomas Nowak, Bernadette Charron-Bost
We survey and discuss upper bounds on the length of the transient phase of max-plus linear systems and sequences of max-plus matrix powers. In particular, we explain how to extend…
AGT, Burge pairs and minimal models
M. Bershtein, O. Foda
We consider the AGT correspondence in the context of the conformal field theory , where is the minimal model based on…
How do autodiffeomorphisms act on embeddings
A. Skopenkov
We work in the smooth category. The following problem was suggested by E. Rees in 2002: describe the precomposition action of self-diffeomorphisms of S^p x S^q on the set of isotop…
Ribbon graphs and bialgebra of Lagrangian subspaces
Victor Kleptsyn, Evgeny Smirnov
To each ribbon graph we assign a so-called L-space, which is a Lagrangian subspace in an even-dimensional vector space with the standard symplectic form. This invariant generalizes…
