Global Existence for Nonlinear Diffusion Equations
Journal of Mathematical Analysis and Applications, 1995 AbstractSolutions of nonlinear (possibly degenerate) reaction-diffusion models are known to exist for all time if the asymptotic growth of the reaction term is not greater than that of the diffusion term. Via concavity methods, it is also known that negating such a condition results in solutions which blow up in finite time.

Global existence and finite time blow-up of solutions to a nonlocal p-Laplace equation
Mathematical Modelling and Analysis, 2019 In this paper a class of nonlocal diffusion equations associated with a p-Laplace operator, usually referred to as p-Kirchhoff equations, are studied.

Global existence for the Seiberg–Witten flow [PDF]
Communications in Analysis and Geometry, 2010 We introduce the gradient flow of the Seiberg-Witten functional on a compact, orientable Riemannian 4-manifold and show the global existence of a unique smooth solution to the flow. The flow converges uniquely in $C^\infty$ up to gauge to a critical point of the Seiberg-Witten functional.

Global existence for semilinear reaction-diffusion systems on evolving domains [PDF]
, 2010 We present global existence results for solutions of reaction-diffusion systems on evolving domains. Global existence results for a class of reaction-diffusion systems on fixed domains are extended to the same systems posed on spatially linear ...

On the Existence of Global Variational Principles
American Journal of Mathematics, 1980 In studying physical phenomena one frequently encounters differential equations which arise from a variational principle, i.e. the equations are the Euler-Lagrangequations obtained from the fundamental (or action) integral of a problem in the calculus of variations. Because solutions to the Euler-Lagrange equations determine the possible extrema of the

Sharp conditions of global existence for nonlinear Schrödinger equation with a harmonic potential
Advances in Nonlinear Analysis, 2019 The Cauchy problem of nonlinear Schrödinger equation with a harmonic potential for describing the attractive Bose-Einstein condensate under the magnetic trap is considered. We give some sufficient conditions of global existence and finite time blow up of

Global boundedness of a higher-dimensional chemotaxis system on alopecia areata
Mathematical Biosciences and Engineering, 2023 This paper mainly focuses on the dynamics behavior of a three-component chemotaxis system on alopecia areata $ \begin{equation*} \left\{ \begin{array}{lll} u_t = \Delta{u}-\chi_1\nabla\cdot(u\nabla{w})+w-\mu_1u^2, &x\in\Omega, t>0, \\ v_t ...

arXiv, 2022 In this note we define and study free global spectra: global spectra with non-trivial geometric fixed points only at the trivial group. We show that free global spectra often do not exist, and when they do, their homotopy groups satisfy strong divisibility conditions. As an application, we show that the universal free $G$-spectrum $EG_+$ does not admit

Global existence for nonlinear operator inclusions
Computers & Mathematics with Applications, 1999 AbstractWe use fixed-point theory for multivalued maps to obtain general existence principles for nonlinear operator inclusions. Our maps are either of upper semicontinuous or lower semicontinuous type.
