We investigate the plexity, inapproximability and approximation algorithms of the problems for finding the minimum number of monochromatic or rainbow subgraphs, such as cliques, cycles, trees and paths, partition V(G) where G avoids some forbidden graphs as subgraphs. 報(bào)告人：閆亮 單位：東南大學(xué)報(bào)告題目：The method of approximate particular solutions for inverse source problems associated with the convectiondiffusion equation摘要：This talk we give a new meshless method based on the method of approximate particular solution我們的報(bào)告主要研究了隨機(jī)動(dòng)力系統(tǒng)的SackerSell譜理論：分別在有限維的情形和無限維的情形下建立了相應(yīng)的SackerSell譜分解定理。通過給出模糊軟集上的三個(gè)運(yùn)算，包括標(biāo)記運(yùn)算、聯(lián)合運(yùn)算以及投影運(yùn)算，證明了模糊軟集族構(gòu)成了一個(gè)信息代數(shù)系統(tǒng)。摘要：This paper is concerned with a mathematical model dealing with a delayed SEIR epidemic model with saturation infection rate. The global dynamics is studied, through constructing suitable Lyapunov functionals and using LaSalle invariant principle. Numerical simulations are also presented to illustrate the results obtained analytically.報(bào)告人：姚紅超 單位：南通大學(xué)理學(xué)院題目：帶變量核的LittlewoodPaley算子交換子在某空間上的有界性報(bào)告人：華洪波 單位：淮陰工學(xué)院報(bào)告題目：On AGX conjectures involving remoteness and proximity of graphs摘要：In this talk, we discuss several AGX conjectures proposed by Aouchiche and Hansen in [M. Aouchiche and P. Hansen, Proximity and remoteness in graphs: results and conjectures, Networks, 58 (2011) 95102.] In particular, we give an extended abstract of the proof of an AGX conjecture.報(bào)告人：劉玉榮 單位：揚(yáng)州大學(xué)報(bào)告題目：多智能體一致性問題摘要：In this talk, the distributed consensus problem is considered for discretetime delayed networks of dynamic agents with fixed topologies, where the networks under investigation are directed and the time delays involved are distributed time delays including a single or multiple time delay(s) as special cases.
