> of values"
>
> *Abstract*: The interplay between groups and fields has been subject of
> study for centuries. With the rise of representation theory we were able to
> consider groups as acting over vector spaces in a natural way, creating a
> new possible connection that relates the irreducibile actions to the field
> generated by the trace of the representation. Those fields give us a lot of
> information about the group itself. In this seminar we will focus on groups
> with field of values that are quadratic extensions of the rationals and we
> will define tools that allow us to detect how far the group is from a
> rational action.

> *Keywords:* Finite groups, representation theory, quasi-rational groups,
> cut groups,Gruenberg-Kegel graph.

> *Information to attend in room 3014*
> The seminar will take place in room 3014, at the building U5-Ratio,
