Incompressible and non-resistive limit of compressible magnetohydrodynamic equations
In this talk, we discuss theincompressible and non-resistive limit for the initial boundary value problemof isentropic compressible resistive magnetohydrodynamic equations withill-prepared initial data in three-dimensional bounded domains. We establishthe higher-order uniform estimates with respect to both the Mach number and theresistivity coefficient in the framework of new type of weighted Sobolevspaces. Thenwe obtain the strong convergence of the magnetic field and thedivergence-free component of the velocityfield, as both the Mach number and the resistivity coefficient tend tozero.

Integral Flows on Graphs and Signed Graphs
A signed graph G is a graph associated with a mapping σ: E(G) →{+1, ?1}. Let G be a graph/signed graph with an orientation on each edge and let A be an abelian group. A function f, from the edge set E(G) of G to the nonzero elements of A, is call an A-flow of G if at each vertex v ∈ V (G), the sum of f(e) over every e with head v is equal to the sum of f(e) over every e with tail v. Tutte conjectured that if a graph has a Z-flow, then it has a Z-flow f such tat |f(e)| ≤ 4 for each e ∈ E(G), which is related to graphs embedded in orientable surfaces. Bouchet conjectured that if a signed graph has a Z-flow, then it has a Z-flow f such tat |f(e)| ≤ 5 for each e ∈ E(G), which is related to graphs embedded in nonorientable surfaces. The theory of flows has a strong connection with the coloring of graphs. In this talk, we focus on recent results on flows of signed graphs.

Ramsey and (bipartite) Gallai-Ramsey numbers for some families of graphs
Given two graphs G and H, the Ramsey number R(G,H) is defined as the minimum number of vertices n such that every red-blue edge-coloring of the complete graph K_n contains either a red copy of G or a blue copy of H. If G is isomorphic to H, then we write R(G) for short. For any positive integer k, the Gallai-Ramsey number gr_k(G:H) is the minimum number of vertices n such that any exact k-edge coloring of K_n contains either a rainbow copy of G or a monochromatic copy of H. The bipartite Gallai-Ramsey number bgr_k(G:H) is the minimum number of vertices n such that for every N greater than or equal to n, any exact k-edge coloring of the complete bipartite graph K_{N,N} contains a rainbow copy of G or a monochromatic copy of H. In this talk, we describe the structures of a complete bipartite graph K_{n,n} without small rainbow subgraphs and determine the Ramsey and bipartite Gallai-Ramsey numbers for some families of graphs.
