    en.wikipedia.org/wiki/Hodge_theory

    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 Riemannian metric on M, every cohomology class has a canonical representative, a differential form that vanishes under the Laplacian operator of the metric.

    Yet another definition of a Hodge structure is based on the equivalence between the -grading on a complex vector space and the action of the circle group U(1). In this definition, an action of the multiplicative group of complex numbers C ∗ {\displaystyle \mathbb {C} ^{*}} viewed as a two-dimensional real algebraic torus, is given on H ...
