Equation(s):$\displaystyle \frac{\partial w}{\partial t}=\frac12\frac{\partial^2w}{\partial x^2}+w^2(1-w)$.
Solution in implicit form:
where the function $F=F(w,t)$ is determined by the system of first-order
partial differential equations
\frac{\partial F}{\partial t}=\frac12 +\frac{3wR}{2(w^2-w-R)},\quad \
\frac{\partial F}{\partial w}=\frac{1}{w^2-w-R},
where the function $R=R(w,t)$ is determined by the implicit formula
Relation (2) is the consistency condition for system (1).
