Global existence and decay estimate of solutions to magneto-micropolar fluid equations
Journal of Differential Equations, 2019 We are concerned with magneto-micropolar fluid equations (1.3) – (1.4) . The global existence of solutions to the Cauchy problem is investigated under certain conditions. Precisely, for the magneto-micropolar-Navier–Stokes (MMNS) system, we obtain global

Global Existence Analysis of Cross-Diffusion Population Systems for Multiple Species [PDF]
, 2016 The existence of global-in-time weak solutions to reaction-cross-diffusion systems for an arbitrary number of competing population species is proved. The equations can be derived from an on-lattice random-walk model with general transition rates.

Global existence for quasilinear wave equations close to Schwarzschild [PDF]
Communications in Partial Differential Equations, 2016 In this article, we study the quasilinear wave equation where the metric is close (and asymptotically equal) to the Schwarzschild metric . Under suitable assumptions of the metric coefficients, and assuming that the initial data for u is small enough, we

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.

ON THE EXISTENCE OF A GLOBAL NEIGHBOURHOOD [PDF]
Glasgow Mathematical Journal, 2015 AbstractSuppose that a complex manifoldMis locally embedded into a higher-dimensional neighbourhood as a submanifold. We show that, if the local neighbourhood germs are compatible in a suitable sense, then they glue together to give a global neighbourhood ofM.

Non-existence of global transverse Poincaré sections [PDF]
Journal of Geometry and Physics, 2021 We study global transverse Poincar sections and give topological conditions for their existence, showing they never exist in many important cases. We prove that an energy hypersurface possessing global transverse Poincar section is equivalent to the hypersuface having a cosymplectic structure.

Global existence, boundedness and stabilization in a high-dimensional chemotaxis system with consumption [PDF]
, 2016 This paper deals with the homogeneous Neumann boundary-value problem for the chemotaxis-consumption system \begin{eqnarray*} \begin{array}{llc} u_t=\Delta u-\chi\nabla\cdot (u\nabla v)+\kappa u-\mu u^2,\\ v_t=\Delta v-uv, \end{array} \end{eqnarray*} in $

Existe realmente o aquecimento global?
Research, Society and Development, 2022 A influência da temperatura nos organismos é um dos aspectos essenciais para a regulação e manutenção da vida. Ao longo do tempo geológico a temperatura na Terra oscilou entre extremos, como consequência de fenômenos geológicos naturais. Porém, especialmente a partir do século XX, algumas atividades antrópicas estão alterando o clima, ocasionando ...
