Infinitesimal generator for the case of a scalar function depending on one variable.
Infinitesimal generator for scalar a function
.
Infinitesimal generator for a pair of functions
.
The set of independent variables can be empty if in the set of the dependent variables functions are given instead.
Infinitesimal generator, when a pair of functions with different dependence,
, and an additional continuous parameter
are involved.
Infinitesimal generator, in characteristic form, including the Jet space of order 2.
The symbol
Q is used for denoting the characteristic form of the infinitesimal generator.
Infinitesimal generator, in characteristic form, including the jetspace up to order 3 for the first variable and up to order 1 for the second.
Infinitesimal generator, in characteristic form, with custom dependence.
Again, in these situations the
ivs set can be empty.
