Published in 2018 at "Aequationes mathematicae"

DOI: 10.1007/s00010-017-0525-4

Abstract: Consider a long, convex, homogenous cylinder with horizontal axis and with a planar convex body K as transversal section. Suppose the cylinder is immersed in water and let $$K_w$$Kw be the wet part of K.… read more here.

Published in 2017 at "Erkenntnis"

DOI: 10.1007/s10670-016-9807-9

Abstract: AbstractIt is well known that the convex hull of the classical truth value functions contains all and only the probability functions. Work by Paris and Williams has shown that this also holds for various kinds… read more here.

Published in 2018 at "Set-Valued and Variational Analysis"

DOI: 10.1007/s11228-017-0428-5

Abstract: We study dentable maps from a closed convex subset of a Banach space into a metric space as an attempt of generalize the Radon-Nikodým property to a “less linear” frame. We note that a certain… read more here.

Published in 2017 at "Set-Valued and Variational Analysis"

DOI: 10.1007/s11228-017-0456-1

Abstract: In this paper, we introduce a new class of nonsmooth convex functions called SOS-convex semialgebraic functions extending the recently proposed notion of SOS-convex polynomials. This class of nonsmooth convex functions covers many common nonsmooth functions… read more here.
