Blow-Up Rate Estimates for a System of Reaction-Diffusion Equations with Gradient Terms
International Journal of Mathematics and Mathematical Sciences, 2019 This paper is concerned with the blow-up properties of Cauchy and Dirichlet problems of a coupled system of Reaction-Diffusion equations with gradient terms. The main goal is to study the influence of the gradient terms on the blow-up profile.

Prescribing Morse Scalar Curvatures: Blow-Up Analysis [PDF]
International mathematics research notices, 2018 We study finite-energy blow-ups for prescribed Morse scalar curvatures in both the subcritical and the critical regime. After general considerations on Palais–Smale sequences, we determine precise blow-up rates for subcritical solutions: in particular ...

Similarity stabilizes blow up [PDF]
Journal of Differential Equations, 1999 This is an extended version of the author's earlier paper [Journées Équations aux Derivées Partielles, Université de Nantes, Exp. No. 12 (1999; Zbl 1004.35062)]. The considered topic is the equation \[ \psi u_t = -L\left( | u| ^{m-1} u \right), \tag{1} \] where \(\psi(x)\) is positive and \(L\) is a self-adjoint strongly elliptic differential operator ...

On the blow-up solutions for the fractional nonlinear Schr\"odinger equation with combined power-type nonlinearities [PDF]
, 2018 This paper is devoted to the analysis of blow-up solutions for the fractional nonlinear Schr\"odinger equation with combined power-type nonlinearities \[ i\partial_t u-(-\Delta)^su+\lambda_1|u|^{2p_1}u+\lambda_2|u|^{2p_2}u=0, \] where ...

Non-self-similar blow-up in the heat flow for harmonic maps in higher dimensions
, 2014 We analyze the finite-time blow-up of solutions of the heat flow for $k$-corotational maps $\mathbb R^d\to S^d$. For each dimension $d>2+k(2+2\sqrt{2})$ we construct a countable family of blow-up solutions via a method of matched asymptotics by glueing a

Advanced Engineering Materials, EarlyView.The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Total blow-up of a quasilinear heat equation with slow-diffusion for non-decaying initial data [PDF]
Mathematica Bohemica, 2019 We consider solutions of quasilinear equations $u_t=\Delta u^m + u^p$ in $\mathbb R^N$ with the initial data $u_0$ satisfying $0 < u_0< M$ and $\lim_{|x|\to\infty}u_0(x)=M$ for some constant $M>0$. It is known that if $0<m<p$ with $p>1$,

The Double Complex of a Blow-up [PDF]
International mathematics research notices, 2018 We compute the double complex of smooth complex-valued differential forms on projective bundles over and blow-ups of compact complex manifolds up to a suitable notion of quasi-isomorphism.

Constructing orders by blowing-up [PDF]
Tsukuba Journal of Mathematics, 1991 Let \(R\) be a noetherian normal domain with quotient field \(K\) and perfect residue class fields for all prime ideals of height one, and \(L| K\) a field extension such that the integral closure \(S\) of \(R\) in \(L\) is finite over \(R\). For a tame \(R\)-order \(A\) in an Azumaya \(K\)-algebra \(\Sigma\), the authors define a ``blowing up'' \(B ...

Development of Aluminum Scandium Alloys for Hydrogen Storage Valves
Advanced Engineering Materials, EarlyView.Different aluminum alloy series and various aluminum‐scandium alloys with differing Sc and Zr levels are evaluated for use in hydrogen storage valve production. The alloys undergo hardness testing, optical microscopy, and tensile strength analysis, with hardening behavior studied under varying conditions.
