A class of tight contact structures on Sigma_2 x I

Tanya Cofer

Abstract. We employ cut and paste contact topological techniques to classify some tight contact structures on the closed, oriented genus-2 surface times the interval. A boundary condition is specified so that the Euler class of the of the contact structure vanishes when evaluated on each boundary component. We prove that there exists a unique, non-product tight contact structure in this case.

Keywords. Tight, contact structure, genus-2 surface
