Nonlocal cross-interaction systems on graphs: Nonquadratic Finslerian structure and nonlinear mobilities
We study the evolution of a system of two species with nonlinear mobility and nonlocal
interactions on a graph whose vertices are given by an arbitrary, positive measure. To this …

[HTML][HTML] Almost isometries of non-reversible metrics with applications to stationary spacetimes
We develop the basics of a theory of almost isometries for spaces endowed with a quasi-

Young measure flow as a model for damage
Models for hysteresis in continuum mechanics are studied that rely on a time-discretised
quasi-static evolution of Young measures akin to a gradient flow. The main feature of this …

On tight spans for directed distances
H Hirai, S Koichi - Annals of Combinatorics, 2012 - Springer
An extension (V, d) of a metric space (S, μ) is a metric space with S ⊆ V and d ∣ _S= μ, and
is said to be tight if there is no other extension (V, d′) of (S, μ) with d′≤ d. Isbell and Dress …

Gradient flows of time-dependent functionals in metric spaces and applications to PDEs
We develop a gradient-flow theory for time-dependent functionals defined in abstract metric
spaces. Global well-posedness and asymptotic behavior of solutions are provided …
