Fractional time differential equations as a singular limit of the Kobayashi-Warren-Carter system

Yoshikazu Giga, Ayato Kubo, Hirotoshi Kuroda +3

This paper is concerned with a singular limit of the Kobayashi-Warren-Carter system, a phase field system modelling the evolutions of structures of grains. Under a suitable scaling…

Graph gradient flows : from discrete to continuum

Yoshikazu Giga, Yves van Gennip, Jun Okamoto

This paper gives a framework to study a continuum limit of a gradient flow on a graph where the number of vertices increases in an appropriate way. As examples we prove the converg…

On a singular limit of the Kobayashi--Warren--Carter energy

Yoshikazu Giga, Jun Okamoto, Koya Sakakibara +1

By introducing a new topology, a representation formula of the Gamma limit of the Kobayashi-Warren-Carter energy is given in a multi-dimensional domain. A key step is to study the…

A finer singular limit of a single-well Modica--Mortola functional and its applications to the Kobayashi--Warren--Carter energy

Yoshikazu Giga, Jun Okamoto, Masaaki Uesaka

An explicit representation of the Gamma limit of a single-well Modica--Mortola functional is given for one-dimensional space under the graph convergence which is finer than convent…

Random discretization of O'Hara knot energy

Jun Okamoto

We considered random discrete approximation of O'Hara energy. O'Hara energy is the energy defined for a knot, and O'Hara energy was introduced for defining the standard shape for e…
