Algebra (Group Theory)

Our research group is mainly interested in Group Theory, which is one of the fundamental branches of Algebra, with numerous applications inside Mathematics, as well as in other areas of science and technology such as physics, chemistry, computer science, or ICT. Our goal is to advance the knowledge of the structure of groups, through the analysis of their factorizations, representations, the lattice of their subgroups and arithmetical properties. This analysis uses techniques of the theory of classes, simple groups, graphs and lattice theory. In the applied side, we are concerned with the interaction of semigroups with automata and formal languages.

Dynamics of operators (DYNOP)

Our group investigates different notions of dynamics (mainly, notions of chaos) for operators and semigroups of operators on spaces of infinite dimension. Precisely, we work on:

(1) Dynamics of C_0-semigroups and applications,

(2) Dynamics of fractional differential (difference) equations,

(3) Li-Yorke chaos and distributional chaos,

(4) Lineability, algebrability and spaceability,

(5) Recurrence in the dynamics of operators,

(6) Dynamics of m-isometries,

(7) Topological and mesure-theoretic properties in linear dynamics,

(8) Numerical simulation and analysis of the dynamics of linear models.

Foreign members: Nilson Bernardes, Juan Bes, Karl Grosse-Erdmann, Carlos Lizama and Piotr Oprocha.

Functional Analysis, Operator Theory and Time Frequency Analysis

Our main research area is the study of methods of functional analysis and operator theory and their applications to several areas of mathematical analysis, like complex analysis, Fourier analysis, dynamical systems, ergodic theory and linear partial differential operators.More precisely, we work in the following problems:

(1) Spaces of analytic and differentiable functions and operators between them: weighted spaces of analytic functions, weighted composition operators, integral operators, Cesàro and Volterra operators.

(2) Time-frequency analysis: Gabortransform, Fourier integral operators, weighted modulation spaces and applications to biomedical nonstationary signals.

(3) Linear partial differential and pseudo-differential operators on spaces of ultradifferentiable functions and ultradistributions: hypoellipticity, regularity of solutions, wave front set and extension of smooth functions.

Interdisciplinary Modelling Group-InterTech

InterTech (www.intertech.upv.es) activities are based on collaborations from researchers of different areas aiming at the creation of new ideas of scientific and technological value. The interdisciplinary nature of the group allows to cover various fields like non-linear optics, in collaboration with the optics department of the Universitat de València; biotechnology; or in the advanced modelling in energetic engineering. As result of the research activities of the group a spin off, Energesis Ingeniería (www.energesis.es), was created fulfilling one of the main goals of InterTech members of transferring the scientific findings to society.

MADPhy: Mathematics and Applications to Data and Physics

The group's activity is focused on the application of the concepts and methods of pure and applied mathematics to different areas of knowledge, which are grouped into two main blocks, Data Science and Physics. It is a multidisciplinary group that involves Mathematicians, Physicists, Documentation Specialists and Engineers. The argument thread of the activity is the elaboration of mathematical models for the analysis of related problems in Functional Analysis and Topology, Bibliometric Indices, Acoustics and Metamaterials, Non-linear Physics, Graph-based databases and Fraud Detection Algorithms, among others.

New Functional and Descriptive Methods in Functional Analysis (NUMAF)

The group is working on:

1.- The Separable Quotient Problem, open problem that states wether a infinite dimensional Banach space admits a Separable Infinite Dimensional Quotient. It is well known that small Banach spaces, I mean with denseness less than the bounding cardinal, as well as the big Banach spaces in the sense of Todorcevic, have separable quotient. Our aim is to get new characterizations of the separable quotient problem and to apply these characterizations to Banach Spaces with denseness between the  bounding cardinal and the continuum cardinal, as well as to apply the new obtained characterizations to proof rapididly the existence of Separable quotient problem, in known cases like in the case of WCG spaces.

2.- The second line of research is the determination of rings and algebras os subsets of a set such that Nikodym property implies more strong Nikodym properties. In other words: When Nikodym property is equivalent to strong and web Nikodym properties? It is well known that this equivalence holds in an sigma-algebra.

Singularity Theory and its Applications

The research topics of our group focus on the study of algebraic and complex analytic singularities. Our research topics include current problems of algebraic geometry, commutative algebra and also some applications to other fields, like the theory of error correcting codes and the theory of foliations. We also deal with the effective computation of numerical invariants of complex analytic maps and the study of notions like equisingularity and topological triviality of deformations of maps.

Topology and its Applications

Our research group is mainly interested in several branches of general topology (asymmetric topology, fixed point theory, fuzzy topological structures, topological algebra, hyperspaces, etc.) as well as its applications to other fields as Computer Science (domain theory, construction of quantitative models, complexity analysis of algorithms) and Image Modelling (image smoothing, image filtering, etc.). We are also concerned with fuzzy set theory always with a topological flavour.
