We prove invariance for the number of planar tropical curves enhanced with polynomial multiplicities recently proposed by Florian Block and Lothar Goettsche. This invariance has a number of implications in tropical enumerative geometry.

Tropical curves in abelian surfaces I: enumeration of curves passing through points
This paper is the first part in a series of three papers devoted to the study of enumerative invariants of abelian surfaces through the tropical approach. In this paper, we consider the enumeration
Refined count for rational tropical curves in arbitrary dimension
In this paper we introduce a refined multiplicity for rational tropical curves in arbitrary dimension, which generalizes the refined multiplicity introduced by Block and Göttsche (Compositio
Brief introduction to tropical geometry
The paper consists of lecture notes for a mini-course given by the authors at the G\"okova Geometry \& Topology conference in May 2014. We start the exposition with tropical curves in the plane and
Floor diagrams and enumerative invariants of line bundles over an elliptic curve
We use the tropical geometry approach to compute absolute and relative GromovWitten invariants of complex surfaces which are CP 1-bundles over an elliptic curve. We also show that the tropical
Tropical refined curve counting from higher genera and lambda classes
It is shown that the result is a generating series of higher genus log Gromov–Witten invariants with insertion of a lambda class, which gives a geometric interpretation of the Block-Göttsche invariants and makes their deformation invariance manifest.
On refined count of plane rational tropical curves by Eugenii Shustin
Motivated by the tropical enumeration of plane cuspidal tropical curves given by Y. Ganor and the author and the refined count of plane rational tropical curves with marked vertices of arbitrary
Quantum indices and refined enumeration of real plane curves
We associate a half-integer number, called {\em the quantum index}, to algebraic curves in the real plane satisfying to certain conditions. The area encompassed by the logarithmic image of such

Gross, Hacking and Keel have constructed mirrors of log Calabi–Yau surfaces in terms of counts of rational curves. Using $q$-deformed scattering diagrams defined in terms of higher-genus log
Tropical curves in abelian surfaces II: enumeration of curves in linear systems
In this paper, second installment in a series of three, we give a correspondence theorem to relate the count of genus g curves in a fixed linear system in an abelian surface to a tropical count. To


Counting plane curves of any genus
We obtain a recursive formula answering the following question: How many irreducible, plane curves of degree d and (geometric) genus g pass through 3d-1+g general points in the plane? The formula is
Enumeration of curves via floor diagrams
Enumerative tropical algebraic geometry
The paper establishes a formula for enumeration of curves of arbitrary genus in toric surfaces. It turns out that such curves can be counted by means of certain lattice paths in the Newton polygon.
Tropical curves, their Jacobians and Theta functions
We study Jacobian varieties for tropical curves. These are real tori equipped with integral affine structure and symmetric bilinear form. We define tropical counterpart of the theta function and
Topological properties of real algebraic varieties: du coté de chez Rokhlin
The survey gives an overview of the achievements in topology of real algebraic varieties in the direction initiated in the early 70th by V. I. Arnold and V. A. Rokhlin. We make an attempt to
Floor decompositions of tropical curves : the planar case
In a previous paper, we announced a formula to compute Gromov-Witten and Welschinger invariants of some toric varieties, in terms of combinatorial objects called floor diagrams. We give here detailed
Tropical geometry and its applications
From a formal perspective tropical geometry can be viewed as a branch of geometry manipulating with certain piecewise-linear objects that take over the role of classical algebraic varieties. This
A Caporaso-Harris type formula for Welschinger invariants of real toric Del Pezzo surfaces
We define a series of relative tropical Welschinger-type invariants of real toric surfaces. In the Del Pezzo case, these invariants can be seen as real tropical analogs of relative Gromov�Witten
Gromov-Witten classes, quantum cohomology, and enumerative geometry
The paper is devoted to the mathematical aspects of topological quantum field theory and its applications to enumerative problems of algebraic geometry. In particular, it contains an axiomatic
The numbers of tropical plane curves through points in general position
Abstract We show that the number of tropical curves of given genus and degree through some given general points in the plane does not depend on the position of the points. In the case when the degree
