ANALYSIS & APPLIED MATHEMATICS

ANALYSIS & APPLIED MATHEMATICS (LINEAR DYNAMICS, SEMIGROUP THEORY, PARTIAL DIFFERENTIAL EQUATIONS, FRACTIONAL CALCULUS & ALGEBRAIC STRUCTURES IN ANALYSIS).

I am working on chaotic dynamics linear operators on infinite-dimensional spaces, from the point of view of Operator Theory and Functional Analysis. These processes can be modelled through PDE’s or infinite systems of coupled ODE’s.  I am also working in the study of large algebraic structures of pathological mathematical objects with nice properties (lineability & algebrability). Recently, I am also interested in Fractional Calculus and its applications.
