A non-linear hyperbolic equation

International Journal of Mathematics and Mathematical Sciences, 1980
In this paper the following Cauchy problem, in a Hilbert space H, is considered: (I+λA)u″+A2u+[α+M(|A12u|2)]Au=fu(0)=u0u′(0 ...

Existence of a unique zero of nonlinear systems

Journal of Numerical Mathematics, 2007
Existence statements for zeros of nonlinear equations are established via the interval Newton method generalizing previous theorems requiring regularity of the inclusion for the Jacobian.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Existence and Uniqueness of a Fixed Point for the Bellman Operator in Deterministic Dynamic Programming [PDF]

We study existence and uniqueness of a fixed point for the Bellman operator in deterministic dynamic programming. We show that removing many of the assumptions of the theorem on the Bellman operator recently shown by Martins-da-Rocha and Vailakis ...

Semipositone elliptic equations in unbounded domains in R n $\mathbb{R}^{n}$

Boundary Value Problems
We investigate a class of semipositone nonlinear elliptic boundary value problems in unbounded domains D of R n $\mathbb{R}^{n}$ , n ≥ 3 $n\geq 3$ . Under some mild-assumptions, we obtain the existence of a unique positive continuous solution and provide

Non-linear biphasic mixture model: Existence and uniqueness results

European Journal of Applied Mathematics
This paper is concerned with the development and analysis of a mathematical model that is motivated by interstitial hydrodynamics and tissue deformation mechanics (poro-elasto-hydrodynamics) within an in-vitro solid tumour.

Sharper existence and uniqueness Results for solutions to Third-order boundary Value Problems

Mathematical Modelling and Analysis, 2020
The purpose of this note is to sharpen Smirnov’s recent work on existence and uniqueness of solutions to third-order ordinary differential equations that are subjected to two- and three-point boundary conditions.

Weak existence and uniqueness for McKean–Vlasov SDEs with common noise [PDF]

Annals of Probability, 2019
This paper concerns the McKean-Vlasov stochastic differential equation (SDE) with common noise, a distribution dependent SDE with a conditional non-linearity.
