摘  要：A symplectic log Calabi-Yau surface is a pair of a closed symplectic 4-manifold and a symplectic divisor representing the anti-canonical class. The symplectic divisor is either a torus or a circular spherical divisor by the adjunction formula. In this talk, We describe the classification of symplectic LCY surfaces and discuss their  contact aspects  (joint works with Cheuk Mak, Jie Min and Shengzhen Ning).
