This is a website for mathematics, from elementary to advanced (mostly algebra and combinatorics).

About me and this website (this includes a FAQ, a CV, and instructions on opening the files on this site).


Abstract Algebra and Combinatorics (papers, preprints and notes)
(including notes on Hopf algebras in combinatorics (joint with Victor Reiner), notes on lambda-rings, and Hopfalgebren (lecture notes after Prof. Hans-Jürgen Schneider, in German), and various exposition and research).

Teaching (classes at the University of Minnesota)
(including homework sets, solutions and sometimes partial notes)

German writings on Elementary Mathematics / Deutschsprachige Aufsätze über Elementarmathematik
(inkl. Arbeiten über Elementargeometrie und Lösungen von Wettbewerbsaufgaben)

Elementary Geometry: Publications and Unpublished notes

Solutions to review problems
(Some problems from American Mathematical Monthly and other sources, with my solutions.)

Other works

A few texts I have written for diverse purposes, arranged according to potential usefulness (i. e., the first in the list are probably the most useful).

Texts written for internet forums:

- MO65420 (sourcecode). This shows some properties of alpha-equivalence and substitution in lambda-calculus that were required for MO question #65420. Already partly obsolete.
