Classical Hodge Decomposition Theorem  
Friday, January 16, 2015  10:00 to 10:45

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 LaplaceBeltrami operator on </span><span><em>p</em>forms on Riemannian manifolds. The decomposition theorem states </span><span>that this space of pforms orthogonally decomposes into the kernel and </span><span>image of the LaplaceBeltrami operator. The short but pretty proof </span><span>uses the ellipticity of the Laplace Beltrami operator together with a </span><span>RellichKondrachovtype theorem and the Hahn Banach theorem.</span></p>
