ANTI-SYMPLECTIC INVOLUTIONS ON NON-KÄHLER SYMPLECTIC 4-MANIFOLDS
ANTI-SYMPLECTIC INVOLUTIONS ON NON-KÄHLER SYMPLECTIC 4-MANIFOLDS
In this note we construct an anti-symplectic involution on the non-<TEX>$K\ddot{a}hler$</TEX>, symplectic 4-manifold which is constructed by Thurston and show that the quotient of the Thurston's 4-manifold is not symplectic. Also we construct a non-<TEX>$K\ddot{a}hler$</TEX>, symplectic 4-manifold using the Gomph's symplectic sum method and an anti-symplectic involution on the non-<TEX>$K\ddot{a}hler$</TEX>, …
