Lie point symmetries of a non linear ODE. Here, substituting
y" is chosen from the way the equation is given:
Lie point symmetries of the KdV equation, here the substitution is chosen automatically:
Lie point symmetries of an ODE including a parameter:
The last case is the most general
Lie point symmetries of a system of ODES:
In this case, the symmetries have been categorized by the value of the parameter
M. The last case is the most general.
For this equation, its Lie point symmetries include also free functions restricted by differential constraint:
Here, the third case is the most general.
Lie point symmetries of a system of PDEs that include integro-differential constraints.
