Since there is no hyperbolic Dehn filling theorem in higher dimension,it is difficult to construct concrete hyperbolic manifolds in dimension at least four.We will talk about eight-colorable small covers over the 120-cell,which give us a set of closed hyperbolic 4-manifolds.This is a joint work with Fangting Zheng.

In this talk Id like to present a couple results on global existence of small amplitude solutions to the system of nonlinear wave equations under the null condition.In particular,quadratic nonlinearit
In this talk,I would like to discuss the blow-up of energy solutions of semilinear wave equations with “non-effective” damping terms including the scale invariant case.It is known that we have such a
In this talk,I will talk about our work on the long time existence of small solutions,for a class of semi-linear wave equations with nonlinearities of the form |u|^q+|u_t|^p,with p,q>1,which is in rel
We consider the Cauchy problem for systems of semilinear wave equationsin two or three space dimensions,with the nonlinearity depending only on derivativesof the unknowns.When the nonlinearity is of t
In this talk,we will discuss about the energy decay problem for the nonlinear dissipativewave equations in one space dimension.It is shown by Mochizuki and Motai(1995)that the decay rate is at least l
This paper is concerned about the lifespan estimate to the Cauchy problem of semilinear damped wave equations withthe Fujita critical exponent in high dimensions$(n\geq 4)$.We establish the sharp uppe
In this mini-course,we discuss special cube complexes and their applications in the study of hyperbolic 3-manifolds.In the first part,we will introduce special cube complexes following Haglund--Wise,a
Let M be a compact interval or a circle.We study algebraic properties of Diff^r(M),the group of C^r diffeomorphisms of M.In the first half of the mini-course,we investigate r=0(homeomorphisms),particu
Around 1980,Thurston showed that "almost every" 3-manifold admits a complete hyperbolic metric.To get such a metric,he proposed to ideally triangulate the manifold and realize each tetrahedron as a hy
The mapping class groups of surfaces can be generated by only torsion elements.This talk will discuss how to reduce the number and the order of such torsion elements.In the case of extended mapping cl
