Real Enumerative Invariants Relative to the Anti-Canonical Divisor and their Refinement
[OWP-2023-02] Itenberg, Ilia; Shustin, Eugenii (Mathematisches Forschungsinstitut Oberwolfach, 2023-03-24)We introduce new invariants of the projective plane (and, more generally, of certain toric surfaces) that arise from the appropriate enumeration of real elliptic curves. These invariants admit a refinement (according to ... -
Tropical Algebraic Geometry
[OWS-35] Itenberg, Ilia; Mikhalkin, Grigory; Shustin, Eugenii (Birkhäuser Basel, 2007)Tropical geometry is algebraic geometry over the semifield of tropical numbers, i.e., the real numbers and negative infinity enhanced with the (max,+)-arithmetics. Geometrically, tropical varieties are much simpler than ...
