Hi all, just a quick question here - the setup is as follows: X is a random variable, X \sim \operatorname{Bin}(m,p) where p=2^{-\sqrt{\log n}}(\log n)^2 and m \geq 2^{\sqrt{\log n}}c for constants c, n (n "large" here). I wish to show that \mathbb{P}(X < c) \leq e^{-(\log...

Let L_1/K,\,L_2/K be extensions of p-adic fields, at least one of which is Galois, with ramification indices e_1,\,e_2 . Suppose that (e_1,\,e_2) = 1 . Show that L_1 L_2/K has ramification index e_1 e_2.

Hello everyone,
I am trying to determine the the threshold function p=p(n) for a random bipartite graph (see http://en.wikipedia.org/wiki/Erd%C5%91s%E2%80%93R%C3%A9nyi_model for a 'random graph': I am interested in the same idea, but for random bipartite graphs), such that...

As the title says, I'm trying to find an efficient algorithm in order to write a program for computing conjugacy classes in subgroups of the general linear group GL(n,\mathbb{F}_p) (n x n matrices over a finite field of p elements, p prime) efficiently. In particular, I am...

As in the question -
Suppose that f_n:[0,1] -> Reals is a sequence of continuous functions tending pointwise to 0. Must there be an interval on which f_n -> 0 uniformly?
I have considered using the Weierstrass approximation theorem here, which states that we can find...
Hi all,
I've been set some holiday work by my study director which is meant to be teaching us all about algorithms and a few other mathematical bits and bobs - unfortunately I've come unstuck on one of the bobs, and was hoping for some help! I've asked for help elsewhere but was given very...
