Gravitational Wave From Axion-like Particle Inflation
Wei Cheng, Tao Qian, Qing Yu +2
In this paper, we investigate the Axion-like Particle inflation by applying the multi-nature inflation model, where the end of inflation is achieved through the phase transition (P…
Local strict singular characteristics: Cauchy problem with smooth initial data
Wei Cheng, Jiahui Hong
Main purpose of this paper is to study the local propagation of singularities of viscosity solution to contact type evolutionary Hamilton-Jacobi equation $$ D_tu(t,x)+H(t,x,D_xu(t,…
Singularities of solutions of Hamilton-Jacobi equations
Piermarco Cannarsa, Wei Cheng
This is a survey paper on the quantitative analysis of the propagation of singularities for the viscosity solutions to Hamilton-Jacobi equations in the past decades. We also review…
Monotone iterative schemes for positive solutions of a fractional differential system with integral boundary conditions on an infinite interval
Yaohong Li, Wei Cheng, Jiafa Xu
In this paper, using the monotone iterative technique and the Banach contraction mapping principle, we study a class of fractional differential system with integral boundary on an…
Weak KAM approach to first-order Mean Field Games with state constraints
Piermarco Cannarsa, Wei Cheng, Cristian Mendico +1
We study the asymptotic behavior of solutions to the constrained MFG system as the time horizon goes to infinity. For this purpose, we analyze first Hamilton-Jacobi equations w…
Singularities of solutions of time dependent Hamilton-Jacobi equations. Applications to Riemannian geometry
Piermarco Cannarsa, Wei Cheng, Albert Fathi
If is a uniformly continuous viscosity solution of the evolution Hamilton-Jacobi equation where is a not necessaril…
