Homeless page


A homeless page is a young courtier who has nowhere to live. I used to be one. Except that I wasn't a courtier...

I was born on another planet. The main country on that planet was called the Union of Soviet Socialist Republics and led the workers of the world - united, no less - to the paradise of communism. My neck of the woods on that planet was called People's Republic of Poland. It was a dreary planet. Look here for one powerful description - by Zbigniew Herbert - of how dreary it was.

But there were universities - relics of better times. I went to one of them: the Jagiellonian University in Krakow. I graduated from the Jagiellonian, worked at the Department of Logic there (a good part of my heart still is in the seminar room where equivalences were proved "towards the stove" and "towards the window"), got my PhD. Meanwhile, on 4 June 1989 a little miracle happened: semi-free elections were held in Poland (exactly on the day of Tiananmen massacre: about a year before the Berlin wall fell). Afterwards, my planet began drifting towards your planet.

In 1998 I moved to Japan Advanced Institute of Science and Technology, where I worked for 5 years. In 2003, I moved to Australia, first to ANU in Canberra, then - after a stint in Italy and Portugal - to Melbourne. I maintain a strong connection with the ALOPHIS group from the University of Cagliari.
Two words that describe what I do: logic and algebra.

Three words that describe what I like: mountains, music and literature. Not necessarily in that order.

Three acronyms that describe what I teach: MAT4MT, MAT3DSA, MAT2ALC. If you do not know what they mean, you are like myself. Acronyms should be banned!

This is the model-theory course link.

There will be links here for Discrete Structures and Algorithms, andĀ  Algebra and Linear Codes, eventually.

Here are slides of some of my talks (well, will be when I put them there, just you wite 'Enry 'Iggins...)

Here is my Research Gate page. And here is the page at Academia.edu.

One more Polish connection - the last one, I promise. Some time ago I came across two books (in Polish), which seriously made the the following claim it would have been better if just before the outbreak of World War II Poland took a strategic move very different from what happened in real history. I was not amused. What I did not likeĀ  was the assumption that making a different strategic move was not only possible, but indeed rational in the circumstances. Well, let's see... moves in strategic games call for a game-theoretic analysis, so here is one dressed in a sci-fi costume to avoid offending sensibilities.



In case you wondered, the picture on the left (properly interpreted) is of a BCK algebra. It shows that BCK algebras do not have CEP (acronyms should be banned!)
