The characterizations on a class of weakly weighted Einstein-Finsler metrics

Xinyue Cheng, Hong Cheng, Pengsheng Wu

In this paper, we study the weakly weighted Einstein-Finsler metrics. First, we show that weakly weighted Einstein-Kropina metrics must be of isotropic S-curvature with respect to…

Some inequalities on Finsler manifolds with weighted Ricci curvature bounded below

Xinyue Cheng, Zhongmin Shen

We establish some important inequalities under a lower weighted Ricci curvature bound on Finsler manifolds. Firstly, we establish a relative volume comparison of Bishop-Gromov type…

On a sinc-type MBE model

Xinyu Cheng, Dong Li, Chaoyu Quan +1

We introduce a new sinc-type molecular beam epitaxy model which is derived from a cosine-type energy functional. The landscape of the new functional is remarkably similar to the cl…

On a parabolic sine-Gordon model

Xinyu Cheng, Dong Li, Chaoyu Quan +1

We consider a parabolic sine-Gordon model with periodic boundary conditions. We prove a fundamental maximum principle which gives a priori uniform control of the solution. In the o…

Global wellposedness for 2D quasilinear wave without Lorentz

Xinyu Cheng, Dong Li, Jiao Xu +1

We consider the two-dimensional quasilinear wave equations with standard null-form type quadratic nonlinearities. We prove global wellposedness without using the Lorentz boost vect…

Uniform boundedness of highest norm for 2D quasilinear wave

Xinyu Cheng, Dong Li, Jiao Xu

We consider the two-dimensional quasilinear wave equations with quadratic nonlinearities. We introduce a new class of null forms and prove uniform boundedness of the highest order…
