Let M, N be two finitely generated modules over a commutative ring, such that is a proper ideal. I try to see why this implies that . How is it done? Is there some bilinear function defined on that we can show not to be the zero function?-- 46.117.106.166 ( talk) 18:59, 23 February 2016 (UTC)

I asked
this question because I store all the pictures I have taken with my
Olympus E-620 DSLR camera in a directory structure in the form AAA/BBBB
where AAA
is a running number from 100 onwards and BBBB
is a number from 0 to 9800, in steps of 200. Olympus digital cameras name their photographs in the form mddnnnn
where m
is the month, from 1 to c (hexadecimal is used to avoid spending an extra digit), dd
is the day of the month and nnnn
is a running number from 1 to 9999. I store all the pictures in the order of the running numbers, making a new AAA
directory every time the counter resets from 1. If a month or year changes in between, I don't care about it.
What is the probability of a single filename occurring in multiple directories, in terms of the number of AAA
directories and the number of years I've been using the camera?
