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 SEMINAR IMPANGA, 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
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...

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."
