Spectral stability of unitary network models - Institut Fourier
We will review the definition of the easy. ?noncommutative geometries? given there, using only the unitary group, the torus and the sphere, by taking into ...
on the infinite fern of galois representations of unitary typeRecently J. Agler studied the class Sd of scalar-valued, analytic functions of d complex variables f for which f(T1 , ..., Td) has norm at most 1 for any ... Unitary easy quantum groups: geometric aspects - Teo BanicaNow, let E be any compact connected subset of Td, and let App(E) ? Td be the set of a ? Td such that a · E admits a very simple approximation (see Lemma 5.15). Spectral asymptotics of semiclassical unitary operatorsT (U) and Td(U) are called the -T-count (T(W)) and -T-depth (Td(W)) of W, respectively. The T-count and T-depth-optimal circuits of U are called ...
