Exponential Growth and Lower Bounds for the Blow-up Time of Solutions for a System of Kirchhoff-type Equations

Journal of New Results in Science, 2019
This paper deals with the system of Kirchhoff-type equations with a bounded domain Ω⊂Rⁿ. We prove exponential growth of solutions with negative initial energy. Later, we give some estimates for lower bounds of the blow up time.

Solving a spectral problem for large-area photonic crystal surface-emitting lasers

Mathematical Modelling and Analysis
We present algorithms for constructing and resolving spectral problems for novel photonic crystal surface-emitting lasers with large emission areas, given by first-order PDEs with two spatial dimensions.

Firms as Bundles of Discrete Resources - Towards an Explanation of the Exponential Distribution of Firm Growth Rates [PDF]

A robust feature of the corporate growth process is the Laplace, or symmetric exponential, distribution of firm growth rates. In this paper, we sketch out a class of simple theoretical models capable of explaining this empirical regularity.

Time‐structured models of population growth in fluctuating environments

Methods in Ecology and Evolution
Although environmental variability is expected to play a more prominent role under climate change, current demographic models that ignore the differential environmental histories of cohorts across generations are unlikely to accurately predict population

Exponential growth of solution for a couple of semi-linear pseudo-parabolic equations with memory and source terms

Journal of Innovative Applied Mathematics and Computational Sciences, 2022
This work is concerned with coupled semi-linear pseudo-parabolic equations with memory terms in both equations, associated with the homogeneous Dirichlet boundary condition.

Stability conditions of chemical networks in a linear framework

New Journal of Physics
Autocatalytic chemical reaction networks can collectively replicate or maintain their constituents despite degradation reactions only above a certain threshold, which we refer to as the decay threshold.
