A Generalized Phase-Field System
Journal of Mathematical Analysis and Applications, 1999 The authors consider the problem \((\Omega\) bounded domain in \(\mathbb{R}^N\) with \(C^2\)-boundary) \[ \begin{aligned} {\partial u\over\partial t}+l {\partial \varphi\over\partial t}=\Delta u+f(x,t), \quad & (x,t)\in Q:=\Omega \times(0,T),\\ {\partial\varphi \over\partial t}=\Delta\varphi+ F(x,t,\varphi) +u,\quad & (x,t)\in Q,\\ {\partial u\over ...

Singular Lagrangians as field systems
Physical Review A, 1995 The singular systems are treated as field systems with constraints. The Euler-Lagrange equations are solved with some constraints. The validity of our proposal has been tested by two examples of singular Lagrangians.
