Expressions

The solution is given through the following expressions:

p1=0


Parameters

Apart from the condition that they must not vanish to give a non-trivial solution and a non-singular solution with non-vanishing denominators, the following parameters are free:
 q4, q3, q2, q1, p2

Inequalities

In the following not identically vanishing expressions are shown. Any auxiliary variables g00?? are used to express that at least one of their coefficients must not vanish, e.g. g0019*p4 + g0020*p3 means that either p4 or p3 or both are non-vanishing.
 
{g0009*q2 + g0010*q1,g0003*q3 + g0004*q1,g0006*q3 + g0007*q2,p2}


Relevance for the application:



The equation: 


f =f *p2
 t  x
The symmetry:
f =D f*f*q1 + D D f *q3 + D f*f*q2 + f  *q4
 s  2          1 2 x       1          2x
And now in machine readable form:

The system:

df(f(1),t)=df(f(1),x)*p2$
The symmetry:
df(f(1),s)=d(2,f(1))*f(1)*q1 + d(1,d(2,df(f(1),x)))*q3 + d(1,f(1))*f(1)*q2 + df(
f(1),x,2)*q4$
