【正文】 is shown to admits a multiparameter ansatz of ellipticalvortex solutions governed by an eightdimensional nonlinear dynamical system. The latter admits an underlying integrable structure of Hamiltonian Ermakov type. Pulsrodon type solutions with a breathertype free boundary oscillation employing the Tikhonov regularization technique. This is a joint work with Fenglian Yang.報(bào)告人：安紅利 單位：南京農(nóng)業(yè)大學(xué)報(bào)告題目：Integrable Ermakov systems in 2+1Dimensional Rotating Shallow Water Theory摘要：A inverse source problem associated with the timedependent convectivediffusive transport equation. The method of approximate particular solution bines the time discretization is presented for the solution of this problem.報(bào)告人：張曉巖 單位：南京師范大學(xué)報(bào)告題目：Minimum Monochromatic and Rainbow Subgraph Partition of Graphs Avoiding Forbidden Subgraphs摘要：Given an edgecolored graph G=(V, E), a subgraph H is said to be monochromatic if all its edges have the same color, and called rainbow if its all edges have distinct colors. 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 然后具體討論一類(lèi)由Levy過(guò)程驅(qū)動(dòng)的隨機(jī)微分方程解的存在唯一性及長(zhǎng)時(shí)間行為以及連續(xù)性問(wèn)題。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(wú)限維的情形下建立了相應(yīng)的SackerSell譜分解定理。報(bào)告人：王廣瓦 單位：江蘇師范大學(xué)報(bào)告題目：隨機(jī)動(dòng)力系統(tǒng)的SackerSell譜摘要：SackerSell譜（又叫動(dòng)力學(xué)譜，或者二分譜）是動(dòng)力系統(tǒng)理論中的一個(gè)重要研究?jī)?nèi)容。通過(guò)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(wèn)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. By using the invariance principle of delay difference systems, a new unified framework is established to deal with the consensus for the discretetime delayed multiagent system. It is shown that the addressed disc
