The continuous wavelet transform. Part I: windowed Fourier transforms.

Abstract: There are several different ways to window the Fourier transform in order to obtain information about when specific frequencies occur. Basically, the idea in all of these is to use a window function to focus the Fourier transform's attention on a specific part of the domain of the function being analyzed, then to move the window function around. In addition to the traditional windows used, one can also view the discrete and continuous wavelet transform as windowed Fourier transforms. This will be discussed and we will try to build motivation for studying the continuous wavelet transform in more general (Lie group) settings.

"Immersed and Virtually Embedded Boundary Slopes for some Arithmetic Manifolds."

Abstract: Suppose we're given a hyperbolic manifold M whose fundamental group is a finite index subgroup of a Bianchi Group.( i.e groups of the form PSL₂(O_d), where O_d is the ring of integers in Q(Ã-d).) We will show that all boundary slopes are realized by immersed, totally geodesic surfaces. It has been known for a while that totally geodesic surfaces lift to embedded surfaces in a finite cover. Thus all slopes for M are virtually embedded boundary slopes.

Symmetric and alternating groups as monodromy groups.

Abstract: Associated to each analytic function f:S-->T between compact Riemann surfaces there is a transitive finite permutation group, called the monodromy group of f. A question of interest is whether fixing the genus of both S and T imposes restrictions on the structure of the monodromy group, both as an abstract group and as a permutation group. Through the work of R. Guralnick and several other authors, it has been seen that the answer to this question is "yes". I will discuss the work just mentioned, featuring my joint work with Guralnick on the case where, as an abstract group, the monodromy group is a symmetric or alternating group.

"The Tits alternative for analytic 4-manifolds of nonpositive sectional curvature"

Abstract: We study subgroups of fundamental groups of real analytic closed 4-manifolds with nonpositive sectional curvature. In particular, we are interested in the following question: if a subgroup of the fundamental group is not virtually free abelian, does it contain a free group of rank two ? The proof uses the theory of general metric spaces of nonpositive curvature.
