Supercharacters for algebra groups and their geometric relations



Description: 
Given any algebra group over any finite field one has a supercharacter theory constructed by P. Diaconis and I.M. Isaacs. And we may ask three questions:  How the supercharacter theory behaves with respect to change of field (i.e. finite field extensions)  Exists an object that contains all supercharacter theory for all changes of field,  If the answer to the second question is positive does exist a group and a supercharacter theory that has the information given by that object. In this talk I will give a brief introduction to the supercharacter theory and give the answer to the questions above.
