 On Types for Unramified \$p\$-Adic Unitary Groups Let \$F\$ be a non-archimedean local field of residue characteristic neither 2 nor 3 equipped with a galois involution with fixed field \$F_0\$, and let \$G\$ be a symplectic group over \$F\$ or an unramified unitary group over \$F_0\$. Following the methods of Bushnell--Kutzko for \$\GL(N,F)\$, we define an analogue of a simple type attached to a certain skew simple stratum, and realize a type in \$G\$. In particular, we obtain an irreducible supercuspidal representation of \$G\$ like \$\GL(N,F)\$.

 Frames and Single Wavelets for Unitary Groups We consider a unitary representation of a discrete countable abelian group on a separable Hilbert space which is associated to a cyclic generalized frame multiresolution analysis. We extend Robertson's theorem to apply to frames generated by the action of the group. Within this setup we use Stone's theorem and the theory of projection valued measures to analyze wandering frame collections. This yields a functional analytic method of constructing a wavelet from a generalized frame multi\-resolution analysis in terms of the frame scaling vectors. We then explicitly apply our results to the action of the integers given by translations on \$L^2({\mathbb R})\$.
