Hodge decomposition of smooth n-forms: is it an isomorphism of topological vector spaces?
Fix a compact Riemannian manifold $M$ (leaving the metric implicit). What I'd like to know is if the corresponding Hodge decomposition of smooth $n$-forms
$$
\Omega^n(M) \simeq \mathcal{H}^n(M)\oplus ...

Why we use Caputo fractional derivative in application?
I'm working on some papers which use Caputo fractional evolution equation (see on Wikipedia) as application for thier main result:
For example:
$$\left\{\begin{matrix}

Differentiability of the Moreau envelope
I've recently come across many results discussing the differentiation of the Moreau envelope defined by
\begin{equation}
e(f)(x)\triangleq \min_{h \in H} \|h-x\|^2 + f(h),
\end{equation}
where $f$ is ...
