Wavelets associated to representations of graph C*-algebras

 Professor Judith Packer

University of Colorado Boulder

 Abstract:  Here we discuss notions of wavelets defined on $L^2$-spaces for fractal-like sets associated to certain representations of graph C*-algebras and higher-rank graph C*-algebras, where the graphs in question are finite and strongly connected.  Generalizing work of M. Marcolli and A. Paolucci, we obtain wavelets using the isometries and partial isometries generating the C*-algebras in question, coming from the graph relations.  We also discuss some related spectral triples.  This work is joint with C. Farsi, E. Gillaspy, A. Julien, and S. Kang.
