WebThere are several ways to show this. I gave this as a homework exercise once (after having given the theory for computing a binomial coefficient modulo two in terms of the binary expansions), and a student surprised me with $$ {2n\choose n}={2n-1\choose n-1}+{2n-1\choose n}=2{2n-1\choose n-1}. WebWe investigate Benford’s law in relation to fractal geometry. Basic fractals, such as the Cantor set and Sierpinski triangle are obtained as the limit of iterative sets, and the unique measures of their components follow a geometric distribution, which is Benford in most bases. Building on this intuition, we aim to study this distribution in more …

WebLet P be a polynomial with integer coefficients and degree at least two. We prove an upper bound on the number of integer solutions n ≤ N to n! = P (x) which yields a power saving over the trivial bound. In particular, this applies to a century-old problem of Brocard and Ramanujan.
