Critical Cohomological Hall Algebra and Edge Contraction
Yiqiang Li, Jie Ren
We study the behaviors of cohomological Hall algebras and relevant subjects under an edge contraction. Given a quiver with potential and fix an arrow, the edge contraction is a way…

Calabi-Yau categories and graded quivers with potential
Jie Ren
We prove that the equivalence classes of d-dimensional Calabi-Yau -categories (dCY category for short) of certain type are in one-to-one correspondence with the gauge equ…

Euler's scheme of Mckean-Vlasov SDEs with non-Lipschitz coefficients
Zhen Wang, Jie Ren, Yu Miao
In this paper, we show the strong well-posedness of Mckean-Vlasov SDEs with non-Lipschitz coefficients. Moreover, propagation of chaos and the convergence rate for Euler's scheme o…
