The dual weighted residual (DWR) method yields reliable a posteriori error bounds for
linear output functionals provided that the error incurred by the numerical approximation of the
dual solution i...

This paper introduces some notions of e ective dimension for weighted
function spaces. A space has low e ective dimension if the smallest ball
in it that contains a function of variance 1, has no fu...

Abstract: We prove some sharp extremal distance results for functions in weighted Bergman spaces on the upper halfplane.We also prove such results in the context of bounded strictly pseudoconvex domai...

We introduce and study a new concept called doubly-weighted pseudo-almost periodicity, which generalizes the notion of weighted pseudo-almost periodicity due to Diagana. Properties of such a new conce...

We study invariance in the class of weighted Lehmer means. Thus we look at triples of weighted Lehmer means with the property that one is invariant with respect to the other two.
