## Abstract In this paper, we combine results on extensions of operators with recent results on the relation between the __M__ ‐function and the spectrum, to examine the spectral behaviour of boundary value problems. __M__ ‐functions are defined for general closed extensions, and associated with re

## Abstract A unified class of linear positive operators has been defined. Using these operators some approximation estimates have been obtained for unbounded functions. For particular linear positive operators these results sharpen and improve the earlier estimates due to Fuhua Cheng (J. Approx. T

The application of density functional theory to complex systems requires simplifications. We describe our methodology, which uses the Harris functional, and its self-consistent generalization to ionic systems as well as its extension to hydrogen-bonded systems. We give brief examples of the applicat
