IDEAL FACTORIZATION 1. Introduction
... course n is not prime, so n = ab with a, b > 1. Then a, b < n, so a and b are products of primes. Hence n = ab is a product of primes, which is a contradiction. Uniqueness of the prime factorization requires more work. We will use the same idea (contradiction from a minimal counterexample) to prove ...

elements of finite order for finite monadic church-rosser
... deciding whether or not a given Thue system has a nontrivial idempotent. Since idempotents are specific elements of finite order, this is a restriction of problem (*). In §2 this restricted problem is solved for finite, special, Church-Rosser Thue systems, and in §3 this solution is extended to fini ...

*7. Polynomials
... The division Theorem above is very similar to a result in integers. Other ideas can be generalized to polynomials such as Definition Let F be one of Q, R, C or Zp , with p prime. Let f, g ∈ F [x] be polynomials not both identically zero. Then a greatest common divisor is a polynomial d ∈ F [x] such ...

Aspects of categorical algebra in initialstructure categories
... the first part, can again be applied in INS-categories, presented to algebraic categories over INS-categories. In particular it is shown that this implies that adjointness of « algebraic» functors over L induces adjointness of « algebraic » functors over an INS-category K . Since furthermore togethe ...

Hodge Cycles on Abelian Varieties
... defined up to sign. A choice of i determines an orientation of C as a real manifold — we take that for which 1 ^ i > 0 — and hence an orientation of every complex manifold. Complex conjugation on C is denoted by or by z 7! z. Recall that the category of abelian varieties up to isogeny is obtained ...

MONADS AND ALGEBRAIC STRUCTURES Contents 1

Étale Cohomology
... Grothendieck was the first to suggest étale cohomology (1960) as an attempt to solve the Weil Conjectures. By that time, it was already known by Serre that if one had a suitable cohomology theory for abstract varieties defined over the complex numbers, then one could deduce the conjectures using th ...
