The Type Ia Supernova and Asymptotic Giant Branch Stellar Ejecta-regulated Interstellar Medium of Massive Galaxies

The Astrophysical Journal
Observations and theory suggest that Type Ia supernovae (SNIa) heating and mass loss from asymptotic giant branch (AGB) stars play a crucial role in the interstellar medium (ISM) of massive galaxies.

Asymptotic profile of solutions of conservation laws with source

Differential and Integral Equations, 1996
The author investigates the Cauchy problem for the following balance law: \(u_t+ f(u)_x= g(u)\), \(x\in \mathbb{R}\), \(t> 0\), with convex flux \(f\) and initial value with compact support. The source function \(g\in C^1\) is supposed to have a finite number of zeros with \(g(0)= 0\) and to satisfy \(g(v)v\leq \alpha v^2+ \beta\) for some \(\alpha\), \

Local decay and asymptotic profile for the damped wave equation in the asymptotically Euclidean setting

We prove local decay estimates for the wave equation in the asymptotically Euclidean setting. In even dimensions we go beyond the optimal decay by providing the large time asymptotic profile, given by a solution of the free wave equation. In odd dimensions, we improve the best known estimates. In particular, we get a decay rate that is better than what

Qualitative properties of traveling wavefronts for a three-component lattice dynamical system with delay

Electronic Journal of Differential Equations, 2019
This article concerns a three-component delayed lattice dynamical system arising in competition models. In such models, traveling wave solutions serve an important tool to understand the competition mechanism, i.e.
