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.
- 3rd Symposium on
Planar Vector Fields. 6-10 september (2010), 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.

research group,
has passed away in november 2005.
