Classical Hodge Decomposition Theorem |
<p><span>I follow the proof in Chapter 6 of Frank Warner's <em>Foundations of </em></span><span><em>Differential Manifolds and Lie Groups</em> of the </span><span class="il">Hodge</span><span> Decomposition </span><span>Theorem. To state the theorem, we take an elegant generalization of </span><span>the Laplacian operator "Delta" to the Laplace-Beltrami operator on </span><span><em>p</em>-forms on Riemannian manifolds. The decomposition theorem states </span><span>that this space of p-forms orthogonally decomposes into the kernel and </span><span>image of the Laplace-Beltrami operator. The short but pretty proof </span><span>uses the ellipticity of the Laplace Beltrami operator together with a </span><span>Rellich-Kondrachov-type theorem and the Hahn Banach theorem.</span></p>
