WITT`S PROOF THAT EVERY FINITE DIVISION RING IS A FIELD
... 3.4. Cardinalities of z(D), D, and z(d). Any ring containing a field may be considered as a vector space over that field. By (8), we may consider z(D) as a vector space over Z/pZ. Being a finite set, z(D) is of finite dimension over Z/pZ, and thus |z(D)| is a power of the prime p. Henceforth, we wri ...

... for the even prime. When these inequalities are satisfied, the Dirichlet series and its Euler product converge in the half–plane Rs > 1 and define an analytic function of s which has no zeros in the half–plane. Another preliminary to the Riemann hypothesis is the analytic extension of the function t ...

Galois Groups and Fundamental Groups
... group is isomorphic to a quotient of the fundamental group of π1 (C \ {1, 5}). (We could have also considered a polynomial like z 3 − 9z 2 + 18z − w, a root of which gives a Galois cubic extension over C(w).) Now C \ {1, 5} is a twice-punctured plane and hence homotopy equivalent to a figure-eight, ...

The Complex Number System The need for extending the real
... The need for extending the real number system is evident when considering solutions of simple equations. For example, the equation x2 + 1 = 0 has no real number solutions, for if x is any real number, then x2 ≥ 0 and so x2 + 1 ≥ 1. We extend the real number system to the system of complex numbers in ...

(The same reasoning motivates algorithms which take matrices as inputs; matrix multiplication is even more expensive). More for ...
