The construction of a new class of approximate wave functions by integral transforms is described. Slater and Gaussian type functions correspond to special. limiting cases of the new class. Some of the conceptuai and practical advantages associated with the new functions are discussed. Recently Par

Abrtract. Sufficient conditions are given such that the product T1T2 of two unbounded operators in Hilbert spaces is essentially selfadjoint and that the nonzero numbers in the essential spectrum of the closure of TlT2 coincide with the nonzero numbers in the essential spectrum of T2T1. If the essen
This paper deals with a new class of perfect FRECHET spaces which can be obtained by interpolation of echelon spaces: Zp,q[am,n]. We determine the reflexive, XONTXL, SCHWARTZ, totally reflexive, totally YONTEL and nuclear spaces Zp.q[am,n]. We also derive results on closed subspaces of the spaces (Z
