IMPANGA

                                                                                                                                                                                                                                                                     Logo designed by M. Donten-Bury and PP

- is an Algebraic Geometry environment created by Piotr Pragacz (PP)
in 2000 at IM PAN (Institute of Mathematics, Polish Academy of Sciences).
IMPANGA is mainly interested in Complex Algebraic Geometry.

                                                                           A goal of IMPANGA is to spread out Algebraic Geometry of good taste among Polish mathematical community.
                                                                                                                         
                                                                       According to Hartshorne:
"To define algebraic geometry, we could say that it is the study of the solutions of systems
                                                                        of polynomial equations in an affine or projective n-space. In other words, it is the study of algebraic varieties.
"


We organize bi-weekly IMPANGA Seminar, which usually takes place at IM PAN in Warsaw
(the word "seminar" is in Latin or Polish "seminarium", and means in Polish "szkolka roslin", i.e., "a school of plants" in English).

From time to time, we work by research groups.

We also organize workshops and conferences.

We publish IMPANGA Lecture Notes and other books.

Alexander Grothendieck (1928 - 2014)

Alexander Grothendieck  passed away on November 13 in the hospital of Saint-Girons (French
Department Ariège) not far from Lasserre, the village where he lived from the early 1990's .

Grothendieck was an extremally important inspiration for us in IMPANGA. In 2004, we dedicated to
him a session
at IM PAN :

Hommage a Grothendieck

with participation of many algebraic geometers, topologists and number theorists.
The first volume of the Impanga Lecture Notes "Topics in cohomological studies of algebraic varieties"
(Birkhauser 2005) was dedicated to Grothendieck. You can download the introductory article
"Notes on life
and work of Alexander Grothendieck" (or its Polish version from Wiad. Mat. 40)  from
my web page. An ameliorated English version appeared in
American Mathematical Monthly 13(9) 2006.

Kinosaki in 2014

Since 40 years Japanese algebraic geometers organize symposia at Kinosaki Onsen (2.5 hour by train
from Kyoto).
The first Kinosaki symposia were organized by T. Miyata and M. Nagata, and S. Mori
(very young at that time) was one of the first speakers. In 2014, the symposium took place on 20-24 October
and was organized by K. Oguiso, H. Ohashi and K. Mitsui. Among the speakers were: K. Yoshioka, B. Fu,
 K. Kawatami, M. Wandel, K. Hashimoto, M. Chen, J. Chen,  Ch. Liedtke, Y. Matsumoto, A. Ito, K. Ueda,
A. Bondal and others. The sessions were chaired by: S. Mukai, S. Mori, Y. Kawamata, T. Saito, K. Saito
 and others. The history of Kinosaki symposia was recalled by T. Oda, M. Miyanishi and T.  Shioda. 

After lectures and onsen (Japanese bath), the participants meet in the hall of  the ryokan Tsutaya Inn
(a Japanese-type hotel with tatami) and discuss various matters with sake
until midnight.
Very fruitful discussions indeed...

Alain Lascoux (1944-2013)   was a good friend to IMPANGA. The attached text is a
memorial writing  for Adv. Stud. Pure Math. 71 "Schubert Calculus - Osaka 2012".

Long in advance: The IMPANGA Seminar on October 18, 2019 will be
dedicated to Alain Lascoux on his 75th anniversary.

IMPA, Rio

 
In Brasil, in Rio de Janeiro, there is a research institute in maths called IMPA (please note that this name is close to IMPANGA ;-) )
They started around 1952. IMPA has a large building (it contains 3 auditoria , several convenient lecture rooms and many
offices for working mathematicians). This year, in April, May and June, IMPA hosted a trimester on algebraic geometry. Algebraic
geometry is not a leading domain at IMPA (this role is played by dynamical systems with A. Avila - a 2014 Fields medalist) ,
but the direction of IMPA understands a leading role of algebraic geometry in contemporary mathematics. Consult the web page:

Trimester of Algebraic Geometry

 

E.g.  the lecturers of this first week of June included: O. Debarre, R. Lazarsfeld and B. Totaro.
PP participated there at two conferences in the 2nd half of May: "Higher dimensional algebraic geometry"
and "Rational points", and also at the "Algebra Seminar" directed by Eduardo Esteves, who was the main
organizer of the trimester.

If you will have an occasion to visit IMPA - do it without hesitation (also coffee there is super!). Near IMPA
there is "Jardim Botanico", an ideal place for meditations and work on maths.

Jerzy Browkin (1934-2015)

When I was a student at Warsaw University (1975-76), Jerzy Browkin teached
me the theory of elliptic curves. He also introduced me to Milnor's K-theory.
Jerzy Browkin was often a guest at the IMPANGA seminar, and especially when
we worked on some arithmetic subject. In 2007, he gave a beautiful lecture on
zeros of the Riemann zeta function. This lecture is written and available (see above
in "Lectures notes of IMPANGA 2007"). His mathematical fatherland was
the arithmetic geometry enviroment in Moscow: Shafarevich, Manin, Parshin
"who was able to present in a few sentences a several pages long proof"...
He also evaluated highly Tate, about whom he reported: "there is such
a mathematician who publishes rarely but is often invited with a lecture
to ICM Congresses."
