Abstract: The estimation of covariance matrices of multiple classes with limited training data is a difficult problem. The sample covariance matrix (SCM) is known to perform poorly when the number of ...

Abstract: In this paper, we introduce a new class of operators between Banach space and Banach lattice called absolutely weakly compact operators, which lies between the classical classes of compact ...

We present a calculation of three point functions for a class of chiral operators, including the primary ones, in d = 3, N = 8; d = 6, N = (2,0) and d = 4, N = 4 superconformal field theories at large ...
