Test Title
Not even under construction. While I collect the will to put something
useful here, please do try a small bridge-building
game or a variaton of box puzzles and mail me with any feedback, comments,
suggestions, bugs, whatever you want. A known problem is that they currently
only work under IE, I have fixed the bridge-building game to function on
FireFox, will do the same with the other one sometime.
Minden esetre: pont-összekötő, egy egyszerű JavaScript
játék (ez meg egy másik: szókirakó),
légy szíves, próbáld ki és írd meg nekem a
véleményedet róla.

Actually, I'll try to do something with this mess.
Planned sections:
Allen Hatcher's page.
Okay, how can I not start by this one? The guy's written darn good books
about algebraic topology and he put them up for everybody to use for
free! I say, that deserves at least a visit to his homepage (and
chances are, you will be staying there for quite a while).
Well, tooting my horn is allegedly an important pastime. So a list of my
papers should be linked here as well. If you're still reading and are
actually interested, here's a short summary:
- ELTE TTK
maths MSci theses have mine, check under year 2004. It's about some
silly messing with level sets (point preimages) of a somewhat weird class of
mappings. There are some really nice results about them (e.g. this one), and thankfully there
are also relatively accessible (if practically unusable) problems that help
young people construct their theses.
- Cobordisms of fold maps and
maps with prescribed number of cusps, contribution to the work of
András Szűcs and Tobias Ekholm. This has been published in Kyushu Journal of
Mathematics, and it's about observing how do the cobordism groups of
manifolds or mappings change if we restrict ourselves solely to "nice" maps
having only regular and fold points.
- Cobordisms of fold maps of 2k+2-manifolds into R3k+2,
submitted to the Proceedings of the Caustics '06 symposium. Same thing, in
another dimension, when the calculations are not quite as simple and easy.
- Calculation of the avoiding ideal for
Σ1,1, to appear in the Proceedings of the M. M.
Postnikov Memorial Conference. Another path for attacking the same problem,
and in the complex setting it actually works all the time. In the real
setting, well, fold maps is the most complicated case where it still works
that I'm aware of.
If you want a copy of either of those papers which don't have a link
attached to them, or just want to talk about maths (any maths, not only
analysis) please e-mail me.
Project Euler. Not really maths, more
compsci, but as long as I don't drag up something fun, it'll do. Maybe I
will be able to get my hands on anatomical images with the parabolic curves
drawn, like in the Hilbert-Cohn Vossen book, those would be fun, right?
I speak Pascal, C/C++, and to some extent, JavaScript. I can also use Excel
to avoid using real languages when I'm lazy and the task at hand is suitable.
I know, I really should put my Travel Cost Calculator for Pardus back
online, but first I think about refactoring and optimizing it (let's face
it, waiting for a minute to get use of four clusters is not user-friendly at
all, and manual update of the map file is like a horse cart in the age of
the superhighways filled with Agents), and then I think about the devs and
that my work may actually contribute to somebody getting involved with the
game and sending them money, so that they can stop working and just enjoy
being unchecked whimsical rulers of their own fantasy domain ... brrrr.
Anyway, if I have enough time and willpower, I'll try to do the refactoring
and set this whole thing free, devs be damned.
Update: I've started working on this again, the current state of affairs is
here.
