comment What options need to be set for Simplify to perform a certain manipulations similar to FullSimplify?
you might want to check out the option TimeConstraint. For example FullSimplify[expr, TimeConstraint -> 1]

Look at Thread[f[a,b]] then %/.f->List.

comment List command separating multiplicative terms
In Wolfram Language there is a VERY big difference between ab and a b. The first is the symbol ab the second is really a*b. When talking about your problem, it would help a great deal to be clear EXACTLY what inputs and outputs you expect.

comment Using Cylindrical coordinates with Graphics3D
@halirutan Those are singular points. If you use the "Mapping" form it doesn't perform the check to see if the point obeys the coordinate range assumptions for that chart. Similarly CoordinateTransform["Spherical" -> "Cartesian", {r, 0, 0}] would give the same message.

Maybe something like delta[v1_, v2_] := Times @@ MapThread[Boole[Equal[##]] &, {v1, v2}]. I am not sure I understand the question.
