Projections onto convex sets on the sphere

Ferreira, O.; Iusem, A.; Németh, S. - In: Journal of Global Optimization 57 (2013) 3, pp. 663-676

In this paper some concepts of convex analysis are extended in an intrinsic way from the Euclidean space to the sphere …. In particular, relations between convex sets in the sphere and pointed convex cones are presented. Several … characterizations of the usual projection onto a Euclidean convex set are extended to the sphere and an extension of Moreau’s theorem …

The W,Z/ν,δ paradigm for the first passage of strong Markov processes without positive jumps

Avram, Florin; Grahovac, Danijel; Vardar-Acar, Ceren - In: Risks 7 (2019) 1, pp. 1-17

As is well-known, the benefit of restricting Lévy processes without positive jumps is the ' W,Z scale functions paradigm', by which the knowledge of the scale functions W,Z extends immediately to other risk control problems. The same is true largely for strong Markov processes X t , with the...
