WARNING: Soon, this site will not be avaliable from http://de.geocities.com/darij_grinberg/ anymore.
Please change your links to
http://www.cip.ifi.lmu.de/~grinberg/ .
(The webhoster, Yahoo Geocities, appears to be closing down. When they have closed, my website will only be avaliable at http://www.cip.ifi.lmu.de/~grinberg/, until I have found a new webhoster.
I am sorry for the inconvenience.)

This website is dedicated to the Geometry of the Triangle, and more generally to Euclidean Geometry. This area of mathematics, standing somewhere between Recreational Mathematics and Algebraic Geometry, today goes through a new resurrection. The renewed interest in Euclidean Geometry can be seen in Clark Kimberling's Encyclopedia of Triangle Centers, in the journal Forum Geometricorum, on Dick Klingens' Geometry pages (Dutch), in the MathLinks forum, or in the Yahoo newsgroup "Hyacinthos" (in honor of the geometer Emile Michel Hyacinthe Lemoine). More links can be found in the link list.

Click here for the FAQ. It can answer some of the questions you wanted to ask me.

This site is currently on two different servers:
http://de.geocities.com/darij_grinberg/ this will soon expire | (2) http://www.cip.ifi.lmu.de/~grinberg/ .
Please use (2) for linking, because server (1) will soon be history.
I have also put the whole website as a ZIP file (well, two ZIP files, to be honest) on Google Sites, because server (2) is not particularly reliable and server (1) is closing down.

Publications, papers, notes

German papers on Elementary Mathematics / Deutschsprachige Aufsätze über Elementarmathematik
(Arbeiten über Elementargeometrie und Lösungen von BWM- und QEDMO-Aufgaben)

Publications - Geometry

Unpublished notes - Geometry

Solutions to review problems
(Some problems from Mathematical Reflections and, from 2010(?) on, American Mathematical Monthly, with my solutions.)

Non-geometric 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; this means that at least from the middle of the list on, you will only find boring bad-written stuff that noone cares about).
