B ACADEMIC HISTORY 6 A RESEARCH ENDEAVOURS I started the topological Galois theory in my PhD. My theory gives the strongest results about unsolvability of algebraic and differential equations in finite terms and provides the topological reasons for such unsolvability. I am one of the creators of the Newton polyhedra theory. I discovered connec- tions between the geometry of Newton polyhedra and the theory of toric vari- eties, results that are now used in both algebraic geometry and combinatorics. I computed many discrete invariants of singularities and of complete intersections using Newton diagrams and Newton polyhedra. This experience in a polyhedral geometry allowed me to prove (jointly with M. Prokhorov) a longstanding con- jecture about absence of a group generated by reflections with a fundamental domain of finite volume in a multidimensional hyperbolic space. Along the same 3 lines is the well known combinatorial analogue of the Riemann-Roch theorem discovered by Pukhlikov and me. It provided the first multidimensional general- ization of the Euler-MacLaurin formula and initiated a broad and very fruitful activity in the geometric community. I also created so called, fewnomial theory. It develops a category of transcenden- tal varieties reminiscent of algebraic geometry. Besides the real algebraic vari- eties, this category contains, for example, graphs of logarithmic and exponential functions. Among applications of this theory, there are my multidimensional version of the classical rule due to Descartes and the solution by Varchenko and me of the Hilbert-Arnold problem about a uniform bound on the number of zeros of abelian integrals. Also Wilkes solution of the longstanding Tarsky problem heavily uses my fewnomials theory. Another area to a large extent motivated by my fewnomials is the recent theory of O-minimal sets. In 1984 I gave an invited talk about this theory at the International Congress of Mathematicians in Warsaw. In the last years together with others I developed the theory of Newton-Okounkov bodies, which provides a new powerful connection between algebra and geome- try. For example, applying it in one direction one can derive a general theorem about systems of algebraic equations from a simple geometric inequality known even to Ancient Greeks. Applying it again in the opposite direction one can derive from this theorem the famous very hard to prove Alexandrov-Fenchel geometric inequality.
