Applications of anticipated BSDEs driven by time-changing Lévy noises
We study a very particular anticipated BSDEs when the driver is time-changing Lévy noise. We give an estimate of the solutions in the system satisfying some non-Lipschitz conditions. Also, we state an useful comparison theorem for the solutions. At last,

A comparison theorem for nonsmooth nonlinear operators
We prove a comparison theorem for super- and sub-solutions with non-vanishing gradients to semilinear PDEs provided a nonlinearity $f$ is $L^p$ function with $p > 1$.

A simple proof of the invariant torus theorem [PDF]
We give a simple proof of Kolmogorov's theorem on the persistence of a quasiperiodic invariant torus in Hamiltonian systems. The theorem is first reduced to a well-posed inversion problem (Herman's normal form) by switching the frequency obstruction from

Oscillation of solutions to fourth-order trinomial delay differential equations
The objective of this article is to study the oscillation properties of the solutions to the fourth-order linear trinomial delay differential equation $$ y^{(4)}(t)+p(t)y'(t)+q(t)y(\tau(t))=0.

In this paper, we consider a nonautonomous predator–prey model with Holling type II schemes and a prey refuge. By applying the comparison theorem of differential equations and constructing a suitable Lyapunov function, sufficient conditions that ...

A Comparison Theorem for Eigenfunctions [PDF]
A comparison theorem of Sturm's type is obtained for eigenfunctions of general linear elliptic partial differential operators of second order on bounded domains of n-dimensional Euclidean space. The proof is almost immediate from an earlier identity of the author. The theorem is shown to be stronger than some recent theorems of Kurt Kreith.

LOGARITHMIC DE RHAM COMPARISON FOR OPEN RIGID SPACES
In this note, we prove the logarithmic $p$-adic comparison theorem for open rigid analytic varieties. We prove that a smooth rigid analytic variety with a strict simple normal crossing divisor is locally $K(\unicode[STIX]{x1D70B},1)$ (in a certain sense)

A comparison theorem for simplicial resolutions
It is well known that Barr and Beck's definition of comonadic homology makes sense also with a functor of coefficients taking values in a semi-abelian category instead of an abelian one.

On Montessus de Ballore’s theorem for simultaneous Padé-Faber approximants
We consider row sequences of vector valued Padé-Faber approximants (simultaneous Padé-Faber approximants) and prove a Montessus de Ballore type theorem.
