HISTORY
|
|
The investigation group was created in the middle
of 1993 and it was initially formed by J. Chavarriga and J.
Giné. Their main objective was to impel the development and the
study of differential equations in the University of Lleida (created
in January 1993). In 1995 the investigation group is consolidated
with the official name Seminari de Sistemes Dinàmics. The same year I.A. García joins the seminar. During the following
years other Ph.D. students as J. Mallol, P. Rodríguez, J. Sorolla
and M. Grau join the seminar as well. Among their main activities
it is worth mentioning their efficient and distinguishable organisation
of the following international congresses:
-
2nd Catalan
Days of Applied Mathematics. 29 november-1
december (1995), Font-Romeu-Odeillo, France.
-
3rd Catalan
Days of Applied Mathematics. 27-29 november
(1996), Lleida, Spain.
-
Symposium
on Planar Vector Fields. 24-27 november
(1996), Lleida, Spain.
-
Winter
School of Dynamical Systems. 27-29 december
(1997), Lleida, Spain.
-
Miniworkshop
on Planar Vector Fields. 12-13 july (2000),
Lleida, Spain.
-
2nd Symposium
on Planar Vector Fields. 17-20 december
(2000), Lleida, Spain.
-
Workshop
on Planar Differential Equations. 11-12
april (2003), Lleida, Spain.
Since 1993
this team has published about seventy articles
and it has been financially supported in part
by diverse entities, as for instance Education
Ministry and Science, Generalitat de Catalunya,
City Council of Lleida, University of Lleida,
Institut d'Estudis Ilerdencs, etc. During
the last decade a wide range of professors
from other international prestigious universities
have been invited. All these professors have
succeeded to developing activities of scientific
character. At this moment the Seminari
de Sistemes Dinàmics is publishing the
international journal Qualitative Theory
of Dynamical Systems specialized in
ordinary differential equations and discrete
dynamical systems. Their main concerns are
devoted to deeply study dynamical systems
in the plane, more precisely, algebraic theory
of integrability (theory of Darboux), the
center-focus problem, isochronous centers,
reversibility, nilpotent and degenerated systems,
bifurcations, limit cycles (16th problem of
Hilbert), Lie symmetries, differential equations
in the complex projective plane, etc.

This note is to inform that Dr. Javier Chavarriga, founder of this research group,
has passed away in november 2005.
Isaac A. García, Jaume Giné, Jordi Sorolla, Josep Mallol and Maite Grau.
