Gradient self-improvement for mixed local and nonlocal parabolic equations

Kenta Nakamura

We introduce a new method for studying gradient higher integrability for mixed local and nonlocal parabolic equations. More precisely, for and , we prove…

Harnack estimates for the nonlocal Trudinger equation

Simone Ciani, Kenta Nakamura

We carry on a study of the point-wise regularity theory for the nonlocal Trudinger equation, with measurable and bounded singular kernel. We establish refined quantitative upper bo…

Nonlocal parabolic De Giorgi classes

Simone Ciani, Kenta Nakamura

We propose a new paradigm for the point-wise regularity theory of parabolic nonlocal problems, by addressing directly the elements of a wide parabolic energy class. First we carry…

Existence for doubly nonlinear fractional -Laplacian equations

Nobuyuki Kato, Masashi Misawa, Kenta Nakamura +1

In this paper we prove the existence of a weak solution to a doubly nonlinear parabolic fractional -Laplacian equation, which has general doubly non-linearlity including not onl…

Harnack's estimate for a mixed local-nonlocal doubly nonlinear parabolic equation

Kenta Nakamura

We establish Harnack's estimates for positive weak solutions to a mixed local and nonlocal doubly nonlinear parabolic equation. All results presented in this paper are provided tog…

Global existence for the p-Sobolev flow

Tuomo Kuusi, Masashi Misawa, Kenta Nakamura

In this paper, we study a doubly nonlinear parabolic equation arising from the gradient flow for p-Sobolev type inequality, referred as p-Sobolev flow. In the special case p=2 our…

Regularity estimates for the p-Sobolev flow

Tuomo Kuusi, Masashi Misawa, Kenta Nakamura

We study doubly nonlinear parabolic equation arising from the gradient flow for p-Sobolev type inequality, referred as p-Sobolev flow from now on, which includes the classical Yama…
