Integration over compact quantum groups

Benoit Collins (CNRS)

Abstract: We find a combinatorial formula for the Haar functional of the orthogonal and unitary quantum groups. As an application, we consider diagonal coefficients of the fundamental representation, and we investigate their spectral measures. Joint work with Theodor Bancica.

The Generic Type of the Heat Equation

Sonat Suer (UIUC Math)

Abstract: Let p be the generic type of \delta_1(y)=delta_2^2(y) in DCF_02. We will prove two things about p. 1. U(p)=\omega but its \Delta-type is 1 and typical \Delta-dimension is 2. This shows that the lower bound in McGrail's thesis is false. We will point out the mistake in her proof. 2. By the first part, p is a regular type. We will show that it is not locally modular and it does not come from a field. That is, if q is the generic type of a definable field in DCF_02, then p and q are orthogonal.
