WebDec 19, 2024 · Hilbert's theorem implies that there exists an algebraic point in any non-empty affine variety. Thus, the set of algebraic points is everywhere dense on the variety and thus uniquely defines it — which is the reason why one often restricts oneself to algebraic points when studying algebraic varieties. References V.I. Danilov WebFeb 20, 2024 · We have included only several topics from the classical invariant theory -- the finite generating (the Endlichkeitssatz) and the finite presenting (the Basissatz) of the algebra of invariants, the Molien formula for its Hilbert series and the Shephard-Todd-Chevalley theorem for the invariants of a finite group generated by pseudo-reflections.

WebHilbert’s niteness theorem led to the stagnation of the eld of classical invariant theory.

The invariants tend to be horrendously complicated polynomials, and the number of them needed as generators can be enormous. In other words rings of invariants are usually too complicated to write down explicitly.
