Connected by Poincaré Inequality - Mufan (Bill) Li

    https://mufan-li.github.io/poincare_inequality/
    Dec 30, 2017 · Quick aside: we say a function has compact support if the set has compact closure. This implies near the boundary.. Observe that the inequality simply bounds the -norm of a function in terms of the -norm of its gradient instead.Note the compact support here is an important assumption when we are integrating with respect to the Lebesgue measure.

Differential forms on a Riemann surface - Wikipedia

    https://en.wikipedia.org/wiki/Differential_forms_on_a_Riemann_surface
    Comment on differential forms with compact support. Note that if ω has compact support, so vanishes outside some smaller rectangle (a 1,b 1) × (c 1,d 1) with a < a 1 < b 1 <b and c < c 1 < d 1 < d, then the same is true for the solution f(x,y). So the Poincaré lemma for 1-forms holds with this additional conditions of compact support.

Poincaré duality - Wikipedia

    https://en.wikipedia.org/wiki/Poincar%C3%A9_duality
    In mathematics, the Poincaré duality theorem, named after Henri Poincaré, is a basic result on the structure of the homology and cohomology groups of manifolds.It states that if M is an n-dimensional oriented closed manifold (compact and without boundary), then the kth cohomology group of M is isomorphic to the (−)th homology group of M, for all integers k

[1101.0313v1] Geometric Poincar\'e Lemma - arXiv

    https://arxiv.org/abs/1101.0313v1
    Abstract: A geometric version of the Poincar\'e Lemma is established for the topological vector space of differential chains. In particular, every differential k-cycle with compact support in a contractible open subset U of a smooth n-manifold M is the boundary of a differential (k+1) -chain with compact support in U. Applications include generalizations of the Intermediate Value Theorem and ...

    Proposition — Let : → be an oriented vector bundle over a manifold and ∗ the integration along the fiber. Then ∗ is ∗ ()-linear; i.e., for any form β on B and any form α on E with vertical-compact support, ∗ (∧ ∗) = ∗ ∧. If B is oriented as a manifold, then for any form α on E with vertical compact support and any form β on B with compact support,
