A geometric approach to nonlocal 2-Hessian equations

Fernando Charro, María del Mar González, María Soria-Carro

We study a nonlocal 2-Hessian equation, given by an infimum of linear deformations of the fractional Laplacian, that is, $in f_{A \in A_{2}} Δ^{s} (u \circ A) (A^{- 1} x)$ . We characterize…

Traveling-wave behavior for Fisher-KPP equations in the hyperbolic space

María del Mar González, Irene Gonzálvez, Fernando Quirós

We study the Cauchy problem in the hyperbolic space for the heat equation with a Fisher-KPP type forcing term. Depending on the relative strength of diffusion, measured by the infi…
