This course will be an introduction to tropical geometry. This is the study tropical varieties which are combinatorial objects (polyhedral complexes) associated to classical algebraic varieties. These objects encode a wealth of information about the original varieties. We will mostly be following the book of D. Maclagan and B. Sturmfels. Topics include: Groebner and Tropical bases, structure of tropical varieties, the fundamental theorem of tropical geometry, tropical linear algebra, matroid theory, toric connections.
