Strong solutions of stochastic differential equations with square integrable drift
Rongrong Tian, Liang Ding, Jinlong Wei
We prove the existence and uniqueness of strong solutions for stochastic differential equations in which the drift coefficient is square integrable in time variable and Hölder cont…

On mountain pass theorem and its application to periodic solutions of some nonlinear discrete systems
Liang Ding, Jinlong Wei, Shiqing Zhang
We obtain a new quantitative deformation lemma, and then gain a new mountain pass theorem. More precisely, the new mountain pass theorem is independent of the functional value on t…
