Group of Simmetries

  1. Apr 23, 2003 #1
    Let be a differntial equation which Lie group of symmetries is A..we will call this differential equation A(y,y´)

    then suppose we perturbe the initial equation A with another differential operator B(y,y´) wich lie group is B.and we form the operator C(y,y´)=A(y,y´)+eB(y,y´) where e<<1 then...

    what would be the lie group of simmetries for C?...

    could it be obtained by perturbation theory?..

    well, the intersection of A nd B would be in the symmetry group of C, for starters...
