WebIntroduction I My talk today is on Hilbert’s Nullstellensatz, a foundational result in the eld of algebraic geometry. I First proved by David Hilbert in 1900. I Pronounced \nool-shtell-en-zatss". I The Nullstellensatz derives its name, like many other German words, from a combination of smaller words: null (zero), stellen (to put/place), satz (theorem). In differential geometry, Hilbert's theorem (1901) states that there exists no complete regular surface of constant negative gaussian curvature immersed in . This theorem answers the question for the negative case of which surfaces in can be obtained by isometrically immersing complete manifolds with constant curvature.

In abstract algebra, Hilbert's Theorem 90 (or Satz 90) is an important result on cyclic extensions of fields (or to one of its generalizations) that leads to Kummer theory. In its most basic form, it states that if L/K is an extension of fields with cyclic Galois group G = Gal(L/K) generated by an element and if is an element of L of relative norm 1, that is then there exists in L such that WebFoliations of Hilbert modular surfaces Curtis T.
