Approximate Analytic Solution to the Three Species Lotka – Volterra Differential Equation Model
Recoletos Multidisciplinary Research Journal, 2021 This paper provides an approximate analytic solution to the three species Lotka – Volterra differential equations by symbolic regression. The approximate analytic solution through symbolic regression is made as close as desired to the actual analytic ...

Analytical Solutions for Expanding Fireballs [PDF]
The Astrophysical Journal, 2008 Many models of gamma-ray bursts (GRBs) as well as of soft gamma repeaters (SGRs) involve a fireball — an optically thick concentration of radiation energy with a high ratio of energy density to rest mass. We study the asymptotic behavior of an ultrarelativistic fireball consisting of electron-positron pairs and photons.

Peierls-Nabarro model of interfacial misfit dislocation: An analytic solution
, 1999 We propose a method to treat the interfacial misfit dislocation array following the original Peierls-Nabarro's ideas. A simple and exact analytic solution is derived in the extended Peierls-Nabarro's model, and this solution reflects the core structure ...
