More generally, we can ask these questions in the setting of Mumford–Tate do-mains. The latter are generalizations of period domains: they are the classifying spaces of Hodge structures with (possibly) non-generic Hodge tensors [12]. As such bts グク いじめHodge theory has become an important tool in algebraic geometry, particularly through its connection to the study of algebraic cycles. While Hodge theory is intrinsically dependent upon the real and complex numbers, it can be applied to questions in number theory. Se mer In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold M using partial differential equations. The key observation is that, given a Se mer Let X be a smooth complex projective manifold, meaning that X is a closed complex submanifold of some complex projective space CP … Se mer Mixed Hodge theory, developed by Pierre Deligne, extends Hodge theory to all complex algebraic varieties, not necessarily smooth or compact. Namely, the cohomology of any complex algebraic variety has a more general type of decomposition, a Se mer The field of algebraic topology was still nascent in the 1920s. It had not yet developed the notion of cohomology, and the interaction between differential forms and topology was … Se mer De Rham cohomology The Hodge theory references the de Rham complex.
