Logo designed by M.
DontenBury 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 nspace. In
other words, it is the study of algebraic varieties.
"
We organize biweekly
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.

groups, sessions and summer seminars,

The two largest events
organized by IMPANGA so far were:

Algebraic Geometry (2010)

Alexander Grothendieck (1928  2014)
Alexander Grothendieck
passed away on November 13 in the hospital of
SaintGirons (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 :
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
2024 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 Japanesetype hotel with tatami) and discuss
various matters with sake until midnight.
Very fruitful discussions indeed...

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
(19342015)
When
I was a student at Warsaw
University (197576), Jerzy
Browkin teached
me the theory of elliptic
curves. He also introduced me to
Milnor's Ktheory.
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."
