    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 publications [74, 75]).

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.

This young Lady showed us how to compete
in sport, but the same applies to mathematics.

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."
