In contextmathematicslang=en terms the difference between invariant and projective
is that
invariant is (mathematics) unaffected by a specified operation (especially by a transformation) while
projective is (mathematics) describing those properties of a figure that are invariant upon projection.
As adjectives the difference between invariant and projective
is that
invariant is not varying; constant while
projective is projecting outward.
As a noun invariant
