Clasificaci\'on de planos torcidos graduados

Abstract

In this thesis, an almost complete classification of all graduated twisted tensorial products of $K[x]$ with $K[y]$ is obtained. We obtain a particular example and three main cases: quadratic algebras, classified by Conner and Goetz by a different method, a family called $A(n,d,a)$ with the property of $(n+1)$-extension for $n>1$, and a third case, not fully classified. Furthermore, in this third case, a family of graded twisted tensor products $B(a,L)$ is obtained, parametrized by a family of quasi-balanced sequences. Members of $B(a,L)$ family do not have the m-extension property, for no $m$. -- En esta tesis se obtiene una clasificaci\'on casi completa de todos los productos tensoriales torcidos graduados de $K[x]$ con $K[y]$. Se obtiene un ejemplo particular y tres casos principales: \'algebras cuadr\'aticas, clasificadas por Conner y Goetz por m\'etodos diferentes, una familia llamada $A(n,d,a)$ con la propiedad de $(n+1)$-extensi\'on para cualquier $n>1$ y un tercer caso no completamente clasificado, para el cual se describen los c\'alculos iniciales que ilustran c\'omo se puede alcanzar la clasificaci\'on de las posibles aplicaciones de torcimiento con una cantidad creciente de c\'alculo computacional. Adem\'as, en este tercer caso, se obtiene una familia de productos tensoriales torcidos graduados $B(a,L)$ parametrizada por una familia de sucesiones casi-balanceadas. Los miembros de la familia $B(a,L)$ no tienen la propiedad de m-extensi\'on, para ning\'un $m$.

Quasi-Whittaker supermodules over Lie superalgebras

In this paper, we develop a general theory of quasi-Whittaker supermodules over Lie superalgebras induced from an arbitrary ideal. We determine the quasi-Whittaker vectors in universal supermodules, establish an irreducibility criterion, and classify several families of irreducible supermodules. The odd part produces a new irreducibility phenomenon absent from the Lie algebra setting. As applications, we determine all irreducible quasi-Whittaker supermodules over the $N=1$ super Schr\"odinger algebra and the $N=1$ $\frac{3}{2}$-conformal Galilei superalgebra, and over the complete spectrum-generating superalgebra in a special case.

Rankin--Selberg integrals of opposite conductor--one newforms

Let $F$ be a nonarchimedean local field of characteristic zero and let $n\geq2$. For $r=n,n+1$, let $\Pi_r$ be an irreducible tempered representation of ${\rm GL}_r(F)$ of conductor one and with trivial central character. We evaluate the Rankin--Selberg integral of opposite newforms in $\Pi_{n+1}\times \Pi_n$ explicitly and show that its central value is nonzero. As an application, this implies a case of Disegni--Zhang's conjecture on the nonvanishing of local relative characters.

Obstructions to Jacobi-Finiteness of Quivers with Potentials

We show that Jacobi-finite potentials need not exist on finite $2$-acyclic quivers. Our main tool is a matrix-valued Golod--Shafarevich--Vinberg inequality for quotients of completed path algebras by finitely many, possibly nonhomogeneous, topological relations. Applied to cyclic derivatives, it yields a potential-dependent obstruction to the finite-dimensionality of completed Jacobian algebras. We then construct a purely quiver-level criterion excluding every Jacobi-finite potential on a given quiver, and exhibit a family of quivers for which every potential has an infinite-dimensional Jacobian algebra.
