Abstract: Abstract New upper bounds on the pointwise behavior of Christoffel function on convex domains in R d are obtained. These estimates are established by explicitly constructing the corresponding “needle”-like algebraic polynomials having small integral norm… read more here.

Abstract: Abstract We investigate densities of vaguely continuous convolution semigroups of probability measures on ℝd{{\mathbb{R}^{d}}}. First, we provide results that give upper estimates in a situation when the corresponding jump measure is allowed to be highly… read more here.
