报告题目：Parabolic implosion surgery and twist deformation of rational maps

报告摘要：Consider the Riemann surfaces of a geometrically finite rational map. A repeated Dehn twist will produce a sequence of rational maps in its moduli space. We will prove that this sequence is convergent under certain condition. The proof involves iteration on Teichmuller spaces and a surgery perturbation which realize a parabolic implosion.

报告人：李琼玲博士后（加州理工学院）

报告题目：Cyclic Higgs bundles and minimal surfaces

报告摘要：Given a G-Higgs bundle over a closed Riemann surface, there is a unique equivariant harmonic map from the universal cover of the Riemann surface into the associated symmetric space of G. We find a maximum principle theorem for a type of coupled linear elliptic systems and apply it to analyze the Hitchin equation for cyclci Higgs bundles. In this case, the harmonic map is conformal and hence minimal. We show several domination results of the pullback metrics of the branched minimal immersion. We also discuss the case Riemann surface with punctures, for example, the uniqueness of harmonic maps.

报告人：尤建功教授（南开大学）

报告题目：Quasi-perodic operators and quasi-periodic cocycles

报告摘要：Quasi-periodic operators has strong background in quantum physics. The eigenvalue equations of the operators define a familyof quasi-periodic cocycles onof the form . The full understanding of the dynamics of this family of cocycles will lead to full understanding of the corresponding operators. In the talk, I will give a brief survey on this topic and present our recent results on the Dry Ten Martini Problem, Aubry-Andre-Jitomirskaya conjecture. The talk is based on joint works with Avila and Zhou.

报告人：Walter Bergweiler professor（ Christian-Albrechts-University of Kiel）

报告题目：Radially distributed values and normal families

报告摘要：We consider functions holomorphic in the unit disk for which all zeros lie on one ray while all one-points lie on a different ray. We show that the family of all these functions is normal in the unit disk punctured at the origin. The case where the zeros are positive and the one-points are negative is studied in more detail. The results are joint work with Alexandre Eremenko.

报告人简介：Walter Bergweiler’s main research area is complex analysis. One topic he is particularly interested in is complex dynamics. This is concerned with the behavior of complex-valued functions under iteration. For example, one studies for which starting values the sequence of iterates converges, whether it has convergent subsequences, etc. The dependence on parameters other than the starting value is also of interest. The corresponding subsets of the complex plane are usually very complicated and they are appealing also to the non-mathematician. Some of these pictures are collected in a gallery. But the mathematics behind them is much more beautiful than the pictures! Other topics in complex analysis where he is interested in are the theory of entire and meromorphic functions, differential and functional equations in the complex domain, quasiregular maps in higher dimension and normal families.
