My Master's Thesis

Applications of the Mellin-Perron Summation formula in number theory.

GZIP compressed PostScript file. (689K) markoriedelthesis.ps.gz and

PDF file. (1.4M) markoriedelthesis.pdf

New! As of March 2009, an addendum to my thesis (outline of an additional chapter). Treats the sum up to some n of the largest odd divisor of k (between 1 and n). Based on a problem from es.ciencia..matematicas, which is here and here. Download it here: addendum1.pdf .

New! As of April 2009, an addendum to my thesis (outline of an additional chapter). Provides an integral formula for the coefficients of a Dirichlet series through Mellin inversion and computes the asymptotics of the sum-of-divisors function. Download it here: addendum2.pdf .

New! As of May 2009, an addendum to my thesis (outline of an additional chapter). Computes the asymptotic expansions of sum_{k=1}^{n-1} sqrt(k(n-k)) and sum_{k=1}^{n-1} 1/sqrt(k(n-k)) through Mellin inversion and shows how to compute the Mellin transforms involved.

Counting nonisomorphic graphs with Polya's theorem

New! As of March 2009, I'm learning Common Lisp. My first exercise was to implement Polya's theorem for the enumeration of nonisomorphic graphs, described in some detail in my GNUstep cookbook. Download the LISP source and a PDF of the results here: polya-graphenum-lisp.tgz .

GNUstep.

Fractal viewer, text formatter based on a2ps, jigsaw puzzle, Minesweeper, and Mastermind game, all of it in Objective C.

New! As of May 2003: the GNUstep cookbook, also here.

GiNaC and MAXIMA

I've used GiNaC to compute various generating functions and MAXIMA to solve differential equations. (My combinatorics page is here.)
