**"Real Algebraic Curves":** The lecture is devoted to the objects that can be described by an algebraic equation f(x, y)=0 in the real plane with Cartesian coordinates x and y (here f is a polynomial in two variables with real coefficients). Examples of such objects are provided by a line (it can be described by a polynomial of degree 1) and an ellipse (it can be described by a polynomial of degree 2). What can be said about curves described by polynomials of higher degrees? In the lecture, we will be mainly interested in topological properties of real algebraic curves.

**"Tropical Geometry":** Tropical geometry is a new mathematical domain which has deep and important relations with many branches of mathematics. It has undergone a spectacular progress during the last ten years. In tropical geometry, algebro-geometric objects are replaced with piecewise-linear ones. For example, tropical curves in the plane are certain rectilinear graphs. We will present basic tropical notions and first results in tropical geometry, as well as applications of tropical geometry in enumerative problems.
