SEMINAR ANNOUNCEMENT

Friday, November 13 2015 at 2.00 p.m.

Andrea Pustetto (University of Trieste)

will speak on
"Decorated Vector Bundles and Tensors".

Abstract: The moduli space for vector bundles, principal bundles and 
many others could be obtained as closed subset of the moduli space of 
tensors. After introducing these objects and their notion of 
semistability, I will make some examples and explain why principal 
bundles and Higgs bundles could be regarded as tensors. Then, I will 
briefly talk about the main known results concerning these objects. 
Finally, I will recall the notion of Harder-Narasimhan filtration for 
vector bundles, talk about the problems which occurs if one tries to 
generalize this notion in the case of tensors and explain some 
possible approaches to the problem.

Venue: Seminar Room  (Sezione di Matematica e Informatica, H2 
building, Via Valerio 12/1, 3rd floor, room 334)
Everybody interested is much welcome to attend.
