Hola todos.
Mañana retomamos las reuniones del seminario de álgebra en el salón de seminarios del IMERL, de 11:00 a 12:30.
En la primer charla contaremos con la exposición de Dag Madsen, de la Universidad de Nordland, que nos va a hablar sobre:
Filtrations in abelian categories determined by tilting objects.
Abstract: A tilting object of projective dimension one in an abelian category determines a torsion pair and consequently every object has a two-step filtration. In joint work with Jensen and Su we discovered that a titling object of projective dimension two determines a triple of disjoint extension closed subcategories subcategories such that every object has a unique functorial filtration of lenght three.
In this talk I will discuss the above result and the generalization due to Jason Lo: A titling object of projective dimension n determines n+1 disjoint extension closed subcategories such that every object has a unique functorial filtration of lenght n+1.
Están todos cordialmente invitados.
Saludos
Ana
