Objective Research activities are related to the following topics.Jacobian Conjecture for polynomial morphisms of affine spaces;Algebraic group actions on affine space.Dual varieties of orbits and generalised discriminants;Standard monomial theory and geometry of Schubert varieties;Constructive methods for invariant theory and representations;Quantum groups with applying methods of algebraic transformation groups;Representation and invariant theories of some remarkable classes of linear actions, and applications;Algebraic geometric properties of algebraic group actions.Objectives and expected results:1. Investigating two representation theoretic approaches to the Jacobian Conjecture and related problems with a view towards proving Mathieu conjecture (at least for some groups) and the corresponding identity for the covariants;2. Investigating nonreductive algebraic group actions on affine space with a view towards finding answers (presumably, negative) to the basic problems (e.g. cancellation problem);3. Describing dual varieties of a class of orbits of linear actions and developing a generalization of the theory of discriminants of linear bundles over flag varieties;4. Investigating some problems related to the general construction of a standard monomial theory for Schubert varieties and involved quantum groups at root of unity, with application to constructing deformations of Schubert varieties for all simple groups;5. Developing methods of constructive Invariant theory with a view towards finding the improved general degree bounds, the relevant computer algorithms and implementations, and the specific explicit descriptions for binary forms, cyclic and symmetric groups;6. Obtaining a canonical presentation by generators and relations for the affine coordinate algebra of a connected reductive algebraic group with a view towards finding its quantization in arbitrary characteristic;7. Developing "quantized shuffle approach" to quantized Kac-Moody algebras and constructing PBW type bases for finite dimensional enveloping algebras at root of unity;8. Investigating orbits and some problems of harmonic analysis for dual pairs, certain classes of prehomogeneous vector spaces, and gradings of Lie algebras;9. Finding new stability criteria for some nonlinear actions;10. Obtaining the combinatorial counterparts of the basic algebraic geometric properties for some natural classes of algebraic transformation spaces;11. Classifying linear actions of connected simple algebraic groups such that the algebra of invariants is a complete intersection;12. Proving equality of essential dimensions of an algebraic group and its Levi subgroup.
