Carolina Vallejo

I am currently a Severo Ochoa postdoctoral researcher at the ICMAT. My main interests are global/local problems in representation theory.

I completed my Ph.D. under the guidance of Gabriel Navarro. The principal object of my Ph.D. thesis was to find explicit bijections between character sets, so that fields of values of characters were preserved.

Submitted

• Even degree characters in the principal block (joint work with E. Giannelli and G. Malle).

In press

• Brauer correpondent blocks with one simple module (joint work with G. Navarro and P.H. Tiep). To appear in Transactions of the American Mathematical Society.

Some beamer talks

I have only used beamer in my first three talks. I don't really like giving beamer talks.
