Quadratic BSDEs with Singular Generators and Unbounded Terminal Conditions: Theory and Applications

Mathematics
We investigate a class of quadratic backward stochastic differential equations (BSDEs) with generators that are singular in y. First, we establish the existence of solutions and a comparison theorem, thereby extending the existing results in the ...

Improved Approach for Studying Oscillatory Properties of Fourth-Order Advanced Differential Equations with p-Laplacian Like Operator

Mathematics, 2020
This paper aims to study the oscillatory properties of fourth-order advanced differential equations with p-Laplacian like operator. By using the technique of Riccati transformation and the theory of comparison with first-order delay equations, we will ...

On Area Comparison and Rigidity Involving the Scalar Curvature [PDF]

, 2013
We prove a splitting theorem for Riemannian n-manifolds with scalar curvature bounded below by a negative constant and containing certain area-minimising hypersurfaces (Theorem 3). Thus we generalise [25,Theorem 3] by Nunes. This splitting result follows

Oscillation theorems for second order neutral differential equations

Electronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper new oscillation criteria for the second order neutral differential equations of the form \begin{equation*} \left(r(t)\left[x(t)+p(t)x(\tau(t))\right]'\right)'+q(t)x(\sigma(t))+v(t)x(\eta(t))=0 \tag{$E$}\end{equation*} are presented. Gained

Heegaard Floer homology as morphism spaces

, 2011
In this paper we prove another pairing theorem for bordered Floer homology. Unlike the original pairing theorem, this one is stated in terms of homomorphisms, not tensor products.

On the Curvature and Heat Flow on Hamiltonian Systems

Analysis and Geometry in Metric Spaces, 2014
We develop the differential geometric and geometric analytic studies of Hamiltonian systems. Key ingredients are the curvature operator, the weighted Laplacian, and the associated Riccati equation.We prove appropriate generalizations of the Bochner ...

${\mathbb{L}}^{\mathit{p}}\mathrm{(}\mathit{p}\ge 2\mathrm{)}$-solutions of generalized BSDEs with jumps and monotone generator in a general filtration

Modern Stochastics: Theory and Applications, 2017
In this paper, we study multidimensional generalized BSDEs that have a monotone generator in a general filtration supporting a Brownian motion and an independent Poisson random measure.
