Whitney coverings and the tent spaces for the Gaussian measure
We introduce a technique for handling Whitney decompositions in Gaussian
harmonic analysis and apply it to the study of Gaussian analogues of the
classical tent spaces of Coifman, Meyer and Stein.Comment: 13 pages, 1 figure. Revised version incorporating referee's comments.

Close-to-convexity of quasihyperbolic and -metric balls
We will consider close-to-convexity of the metric balls defined by the
quasihyperbolic metric and the -metric. We will show that the -metric
balls with small radii are close-to-convex in general subdomains of \Rn and
the quasihyperbolic balls with small radii are close-to-convex in the punctured
space.Comment: 12 pages, 2 figure
