Complex and Symplectic Geometry This book arises from the INdAM Meeting Complex and Symplectic Geometry which was held in Cortona in June 2016. Several leading specialists including young researchers in the field of complex and symplectic geometry present the state of the art of their research on topics such as the cohomology of complex manifolds; analytic techniques in Kähler and non Kähler geometry; almost complex and symplectic structures; special structures on complex manifolds; and deformations of complex objects. The work is intended for researchers in these areas 1 Generalized Connected Sum Constructions for Resolutions of Extremal and KCSC Orbifolds 2 Ohsawa Takegoshi Extension Theorem for Compact Kähler Manifolds And Applications 3 TBA 4 The Monge Ampère Energy Class E 5 Quasi Negative Holomorphic Sectional Curvature and Ampleness of the Canonical Class 6 Surjective Holomorphic Maps onto Oka Manifolds 7 Stabilized Symplectic Embeddings 8 On the Obstruction of the Deformation Theory in the DGLA of Graded Derivations 9 Cohomologies On Hypercomplex Manifolds 10 The Teichmüller Stack 11 Embedding of LCK Manifolds with Potential into HOPF Manifolds using Riesz Schauder Theorem 12 Orbits of Real Forms Matsuki Duality and CR Cohomology 13 Generalized Geometry of Norden and Para Norden Manifolds 14 Spectral and Eigenfunction Asymptotics in Toeplitz Quantization 15 On Bi Hermitian Surfaces 16 Kähler Einstein Metrics on Q Smoothable Fano Varieties their Moduli and some Applications 17 Cohomological Aspects on Complex and Symplectic Manifolds 18 Towards the Classification of Class VII Surfaces
