To see this we consider another perturbed Laplacian operator for arbitrary
positive integers p and N . The unperturbed operator is one that gives rise to a set
o ( t ) = 22 V ? ; ( t ) , j = 1 , . . . , p , of diffusion equations which occur in the theory

Thus the Gelfand theory gives a general procedure for determining whether or
not an element possesses an inverse and ... this procedure to a given algebra , it
is sufficient to give a satisfactory representation of its spectrum and the functions
