Algorithmic reduction of polynomially nonlinear PDE systems to parametric ODE systems
Siyuan Deng, Michelle Hatzel, Gregory Reid +2
Differential-elimination algorithms apply a finite number of differentiations and eliminations to systems of partial differential equations. For systems that are polynomially nonli…
