adjoint: % -> % if R has CommutativeRing

adjoint(op) returns the adjoint of the operator op.

adjoint: (%, %) -> % if R has CommutativeRing

adjoint(op1, op2) sets the adjoint of op1 to be op2. op1 must be a basic operator

conjug: R -> R if R has CommutativeRing

conjug(x)should be local but conditional

elt: (%, M) -> M

from Eltable(M, M)

evaluate: (%, M -> M) -> %

evaluate(f, u +-> g u) attaches the map g to f. f must be a basic operator g MUST be additive, i.e. g(a + b) = g(a) + g(b) for any a, b in M. This implies that g(n a) = n g(a) for any a in M and integer n > 0.
