GroupFromAlgebra

GroupFromAlgebra[l]
gives the action of the local group that corresponds to the infinitesimal generator l. In other words, performs the exponentiation for this element of the Lie algebra.
  • GroupFromAlgebra returns either the list of the local group transformations depending on the variable or the system of ODEs needed to be solved. The variables that do not change under the action of the local group are not included.
