On Bennequin Type Inequality for Symplectic Caps of (S3,ξstd).

In this talk I will discuss a Bennequin type inequality for symplectic caps of S3 with standard contact structure. This has interesting applications which can help us to understand the smooth topology of symplectic caps and smoothly embedded suraces inside this. This is a joint work with Masaki Taniguchi and Nobuo Iida.
