报告摘要: We introduce the frames for Banach and operator spaces, show the equivalence with the bounded approximation property and complemented embedding for operator spaces, and give the duality theorems for frames and associated basis in reflexive spaces. We give a concrete example for reduced free group C*-algebra. Motivated by the connection between the analysis of dual pairs of frames (both the discrete and the continuous theory) and general dilation theory of operator-valued measures on Banach spaces, we give the corresponding fundamental dilation theorems for various operator-valued systems, such as, imprimitivity with a projective isometric group action,  OVMs with bounded p-variation. Furthermore, we obtain (Jordan) dilation theorem from commutative vN algebras to non-commutative case.
