Existence of positive solutions to semilinear elliptic systems with supercritical growth [PDF]

open access: yes, 2016
We establish the existence of positive entire solutions to cooperative systems of semilinear elliptic equations involving nonlinearities with critical and supercritical growth.

Interior estimates of derivatives and a Liouville type theorem for Parabolic $k$-Hessian equations

open access: yes, 2022
In this paper, we establish the gradient and Pogorelov estimates for $k$-convex-monotone solutions to parabolic $k$-Hessian equations of the form $-u_t\sigma_k(\lambda(D^2u))=\psi(x,t,u)$.

SSME Long-life Bearings [PDF]

open access: yes
Hybrid hydrostatic/ball bearings for LH2 and LO2 service in turbopumps were studied as a means of improving speed and life capabilities. Four hybrid bearing configurations were designed with emphasis on achieving maximum stiffness and damping.

On global solutions of quasilinear second-order elliptic inequalities

open access: yes
We consider the inequality $$ - \operatorname{div} A (x, \nabla u) \ge f (u) \quad \mbox{in } {\mathbb R}^n, $$ where $n \ge 2$ and $A$ is a Caratheodory function such that $$ C_1 |\xi|^p \le \xi A (x, \xi) \quad \mbox{and ...

Uniqueness and nonlinear stability of entire solutions in a parabolic-parabolic chemotaxis models with logistic source on bounded heterogeneous environments

open access: yes
This paper studies the asymptotic behavior of solutions of the parabolic-parabolic chemotaxis model with logistic-type sources in heterogeneous bounded domains: \begin{equation*} \label{u-v-eq00} \begin{cases} u_t=\Delta u-\chi\nabla\cdot (u \nabla v ...
