A supersolutions perspective on hypercontractivity [PDF]
The purpose of this article is to expose an algebraic closure property of supersolutions to certain diffusion equations. This closure property quickly gives rise to a monotone quantity which generates a hypercontractivity inequality. Our abstract argument applies to a general Markov semigroup whose generator is a diffusion and satisfies a curvature ...

Minimal supersolutions of BSDEs with lower semicontinuous generators [PDF]
We study the existence and uniqueness of minimal supersolutions of backward stochastic differential equations with generators that are jointly lower semicontinuous, bounded below by an affine function of the control variable and satisfy a specific normalization property.

Fractional Kirchhoff-Type and Method of Sub-supersolutions
In the present paper, we are interested in investigating the existence of positive solutions of a new class of fractional Kirchhoff via the sub and supersolutions technique. For this, we first need to investigate two results through lemmas.

Dual representation of minimal supersolutions of convex BSDEs
We give a dual representation of minimal supersolutions of BSDEs with non-bounded, but integrable terminal conditions and under weak requirements on the generator which is allowed to depend on the value process of the equation. Conversely, we show that any dynamic risk measure satisfying such a dual representation stems from a BSDE.

Supersolutions for a class of semilinear heat equations [PDF]
A semilinear heat equation $u_{t}=Δu+f(u)$ with nonnegative initial data in a subset of $L^{1}(Ω)$ is considered under the assumption that $f$ is nonnegative and nondecreasing and $Ω\subseteq \R^{n}$. A simple technique for proving existence and regularity based on the existence of supersolutions is presented, then a method of construction of local and
