Hilbert`s Nullstellensatz and the Beginning of Algebraic Geometry
... n = 1 is easy, because for single variable polynomial rings k[X], one can divide one polynoinial f by another polynomial 9 of degree deg 9 = d and get a remainder T such that either T = 0 or deg T < d. The proof given in (ii) of example 2.3 above to show that all ideals in Z are principal (singly ge ...

... Non-standard analysis is a branch of mathematics that formulates analysis using a rigorous notion of infinitesimal, where an element of an ordered field F is infinitesimal if and only if its absolute value is smaller than any element of F of the form n1 , for n a natural number. Ordered fields that ...
