introduction
Dynamical systems theory looks for the milestones that organize dynamics, essentially their invariant objects and their connections. In this ambitious goal, the group has a recognized track record and a leading role, addressing it through, among others, analytical, geometrical, topological, or numerical tools, which, complemented, also contribute to a deeper understanding of the dynamics of a system. The dynamics of the systems studied, which are real or complex, can be both discrete and continuous, their dimensions are low or high, depending very much on the specific applications.
In low-dimensional systems, the search for periodic orbits and their repercussions on global dynamics is of paramount importance, especially as a result of the associated symbolic, topological, and combinatorial dynamics. The computational and numerical implementation for looking the phase portraits and bifurcation diagrams is also widely used in modelization and other applications.
In high-dimensional systems, the search for invariant tori and their disposition into normally hyperbolic invariant objects is studied especially to describe the skeleton from which emanates global dynamics, such as KAM theory, Arnold diffusion, and associated exponentially small phenomena, with special attention to applications in Celestial Mechanics, Astrodynamics, Neuroscience, and Chemistry.

Armengol Gasull
My main interest is the understanding of the global behaviour of dynamical systems. I have been working on differential equations (autonomous or not) and on discrete dynamical systems, with special emphasis on difference equations. In my research, apart from the general theory of dynamical systems, I use techniques of analysis, geometry, algebra, algebraic geometry, numerical analysis and simulation.
I have published more than 100 papers collaborating with 45 researches around the world. Together with some of them I have solved several conjectures: the Markus-Yamabe Conjecture about global asymptotic stability of differential equations, open since 1960; the Composition Conjecture appearing in the study of Abel equations; and a conjecture of E. C. Zeeman about the existence of rational 9-periodic points for the Lyness recurrence. I also have contributed to the qualitative theory of planar differential equations, with my results on the number of limit cycles and the period function.
Recently, my joint paper, A. Cima, A. Gasull and V. Mañosas, Basin of attraction of triangular maps with applications, has received the prize to the best paper published in Journal of Difference Equations and its Applications during 2014.

Pau Martin
Early works, under the supervision of Ernest Fontich, dealt about the problem of abundance of Arnold difussion in the context of analytic Hamiltonian systems. Besides proving the density of systems with exhibiting such behaviour, several tools were developed that have been used afterwards by several authors.
Related to the problem of instability, the splitting of separatrices has also been studied, both for area preserving maps and Hamiltonian systems of higher dimension.
As a consequence of these last developments, recently a prove has been found of the existence of oscillatory motions in the restricted planar circular three body problem for all values of the mass paramenter, closing a long standing problem.
Tere Martínez Seara
Tere M-Seara is full professor at the Dpt. de matemàtiques of the Universitat Politècnica de Catalunya. She is the leader of the UPC Dynamical Systems group, formed by more than 20 researchers working on theoretical and computer aspects of finite and infinite Dynamical Systems, with focus on Celestial Mechanics and mathematical Neuroscience. She has supervised 8 PhD. students. In 2015, she received the first Barcelona Dynamical Systems Prize and in the fall of 2018 she hold an Eisenbud Professorship (Simons Foundation) at MSRI (U. Berkeley).
She belongs to the editorial board of Nonlinearity, SIADS, NOdea; SEMA-SIMAI Springer series and has published about 60 papers including articles in the journals: Adv. Math., Comm. Math. Phys, Comm. Pure and Applied Math., Inventiones Mathematicae, J. of Differential Equations, J. of Nonlinear Science, Memoirs of the A.M.S.
Tere M-Seara works in Dynamical Systems, in analytical tools to study their global dynamics.
Her works developed two tools which have been widely used in the area of Arnold Diffusion: the study of normally hyperbolic invariant manifolds and the theory of the “scatering map”.
She also works in a rigourous approach to singular perturbation theory: developing methods which allow to measure exponentially small phenomena which are relevant in the study of the global dynamics of a system like the exponentially small splitting of separatrices, one of the main phenomena producing chaos.
