A Note on Submaximal Operator Space Structures,In this note, we consider the smallest submaximal space structure .(.) on a Banach space .. We derive a characterization of .(.) up to complete isometric isomorphism in terms of a universal property. Also, we show that an injective Banach space has a unique submaximal space structure and we explore some duality relations of .-spaces.

The Berezin Number, Norm of a Hankel Operator and Related Topics, the Berezin number a new inequality for the norm of the Hankel operator . which is better than the classical inequality . The Berezin number is also used to generalize the Douglas lemma on zero Toeplitz products.

Coherent States and Wavelets, a Contemporary Panorama,ed by Glauber, Klauder and Sudarshan in the 1960s, we proceed to the derivation of general CS from square integrable group representations and some of their generalizations: Perelomov CS, general square integrable covariant CS, nonlinear CS, Gazeau–Klauder CS, with a hint to their application in qua
