Areas of specialization Mathematics (Algebraic Geometry)
Laboratory/research office Mathematics (Algebraic Geometry) Laboratory
Algebraic geometry is the area of mathematics engaged in the classical study of geometric figures defined by polynomials, for example, conics (ellipses, hyperbolas and parabolas), which are plane curves of a special type and have been extensively studied. Our research focuses primarily on algebraic curves (one-dimensional algebraic varieties).
