DOI: 10.1007/s11222-017-9772-4

Abstract: Kernel smoothing of spatial point data can often be improved using an adaptive, spatially varying bandwidth instead of a fixed bandwidth. However, computation with a varying bandwidth is much more demanding, especially when edge correction… read more here.

DOI: 10.1016/j.jfa.2016.12.023

Abstract: Abstract In this paper we deal with the Cauchy problem associated to a class of nonlinear degenerate parabolic equations, whose prototype is the parabolic p -Laplacian ( 2 p ∞ ). In his seminal paper,… read more here.

DOI: 10.1515/forum-2017-0192

Abstract: In this paper, we establish existence and uniqueness of weak solutions to general time fractional equations and give their probabilistic representations. We then derive sharp two-sided estimates for fundamental solutions of a family of time… read more here.
