'''Rui Wang''' ''The canonical connection on contact manifolds and an tensorial proof of exponential decay ''
'''name''' ''title ''
 
Abstract:
 
We define a new connection on contact manifolds and give the proof of its existence and uniqueness. This is an odd dimensional analogue of canonical connection defined by Ehresman-Libermann’s  on the almost K ̈ahler manifolds. We call it the canonical connection on contact manifolds. Further from the canonical connection, we construct a Hermitian connection of the pull back bundle w^*\xi. In the sequential talk, I use this Hermitian connection to give a tensorial way to derive the exponential decay of pseudo-holomorphic curves with gradient bound. This is a joint work with Yong-Geun Oh.
 
'''Dongning Wang''' ''Quantum Cohomology Ring of Toric Orbifolds via Seidel Representation''
 
Abstract:
 
We compute the Seidel elements for toric orbifolds, and use them to show that the quantum cohomology ring of toric orbifolds is isomorphic to the quotient of a polynomial ring generated over novikov ring by certain relations. This result is for all toric orbifolds. If the toric orbifold is Fano or Nef, then the isomorphism can be written down explicitly. This is a joint work with Hsian-Hua Tseng.

Abstract:


I will talk about spectral invariants, related invariants and area conjecture proposed by Prof. Oh in his paper: Spectral invariants, analysis of the Floer moduli space, and geometry of the Hamiltonian diffeomorphism group.
