IMPANGA
    
is an algebraic geometry seminar, created at IM PAN in 2000.
      Since 2020, I am Honorary Chairman of Impanga.

      *****

       Accademia Peloritana dei Pericolanti in Messina, created in 1729,
       is one of the most remarkable Academies of the world.  Its
       Corresponding Member was, e.g., S.-S. Chern - my mathematical
       hero, and many others.
Since 2016, I am Corresponding Member of
   Accademia Peloritana dei Pericolanti

I am interested in formulas (mainly algebraic)
that give us interesting insights to geometry.

For the moment, I am interested in comparison of the Łojasiewicz
exponent and the order of tangency (see [74,75] on my list of publications).

My professional activity, since 2000, is related to IMPANGA

Lao Tsy "Droga":

Prawdziwą służbą Mędrca
Jest pracować w milczeniu,
Bo nie racje, lecz spełnienia
Są nauką tego, który
Wszystkim jednakowo służy.

Każdemu użycza, nie odrzucając nikogo,
Ożywia tysiące rzeczy, nie próbując ich posiadać,
A co pozostawia przechodząc,
Niczym go nie wiąże.

Chociaż wiele ma zasług,
nie przyjmuje wyróżnień.
Dlatego zawsze jest wyróżniony.

About the front page: the picture there shows some detail of my garden. I share the opinion
of Hermann Fuerst von Pueckler-Muskau (1785-1871), who once said:
''Wer mich ganz kennenlernen will, muss meinen Garten kennen, denn  mein Garten ist mein  Herz."
