Additional Staff
Complex differential geometry, algebraic geometry, global analysis. Research interests: Set-valued mappings, selections, hyperspaces, absolute extensors and retracts, embedding-like properties, finite-dimensional and infinite-dimensional spaces. Riemannian and almost Hermitian manifolds, theory of submanifolds, differential geometry of surfaces in a 3-dimensional and in a 4-dimensional Euclidean or pseudo-Euclidean space. Fractional Calculus, Special Functions, Integral Transforms, Differential Equations. Approximations by rational functions in the complex plane: Pade approximation, best rational approximation, orthogonal polynomials, rate of approximation; complex analysis, potential theory, numerical analysis, mathematical modelling. Several complex variables, Analysis on complex and almost complex manifolds, Complex differential geometry, Twistor theory. Fractional Calculus, Special Functions, Integral Transforms, Differential Equations. My research has been in the area of arc and jet schemes, motivic integration, and their applications to singularities, such as Nash problem. Also, I am working in topology of complements of algebraic sets, including generalizations of Zariski - van Kampen theorem for higher homotopy groups, and hyperplane arrangements. Recently started my interest in applications of singularities of differentiable maps to medical imaging. Algebraic geometry and commutative algebra, and their interactions with deformation theory and singularity theory. Nonlinear functional analysis, critical points theory, private and ordinary differential equations, differential equations, fractional calculus and differential equations of fractional order. Geometry of Banach spaces and related aspects of approximation theory, topology, probability theory, descriptive set and function theory.
