Web1960s Grothendieck defined etale cohomology and crystalline cohomology, and showed that´ the algebraically defined de Rham cohomology has good properties in characteristic zero. The problem then became that we had too many good cohomology theories! Besides the usual valuation on Q, there is another valuation for each prime number ‘ defined by WebFeb 9, 2015 · Grothendieck Group. Let A = Z be a ring, K = Q its field of fractions, L a number field, and B = O L, the integral closure of A in L. Define the category C A of A -modules of finite length via composition series. Since each M j / M j − 1 is simple we can say that M j / M j − 1 = A / p j for some prime ideal. Furthermore, this choice of ...
