Global Kodaira-Spencer class and Massey products
Luca Rizzi, Francesco Zucconi

Abstract. We define a new notion of supported global deformation class for a semistable family of complex varieties over a curve f:X→B. We use this notion to study when X, possibly up to a finite covering, has a generically finite morphism onto a product B ×Y with Y of general type
