Algebraicity of Hodge Loci for Variations of Hodge Structure
Artículo
Acceso abierto Artículo CONICET Digital
Cattani, Eduardo et al · American Mathematical Society · 2014 · ISSN 0271-4132
These notes should be seen as a companion to [8], where thealgebraicity of the loci of Hodge classes is proven without appealing to theHodge conjecture. We give explicit detailed proofs in the case of variationsof Hodge ...
