Bold Feynman diagrams and the Luttinger-Ward formalism via Gibbs measures. Part II: Non-perturbative analysis
Lin Lin, Michael Lindsey
Many-body perturbation theory (MBPT) is widely used in quantum physics, chemistry, and materials science. At the heart of MBPT is the Feynman diagrammatic expansion, which is, simp…

A Stochastic Generalized Ginzburg-Landau Equation Driven by Jump Noise
Lin Lin, Hongjun Gao
This paper is concerned with the stochastic generalized Ginzburg-Landau equation driven by a multiplicative noise of jump type. By a prior estimate, weak convergence and monotonici…
Decay estimates of discretized Green's functions for Schrödinger type operators
Lin Lin, Jianfeng Lu
For a sparse non-singular matrix , generally is a dense matrix. However, for a class of matrices, can be a matrix with off-diagonal decay properties, i.e. $\lv…
