چکیده
We introduce a tropical geometric framework that allows us to define $\psi$ classes for moduli spaces of curves arbitrary genus. prove correspondence theorems between algebraic and some one-dimensional families genus-one curves.

Integrals of ψ-classes over double ramification cycles
DR-cycles are certain cycles on the moduli space of curves. Intuitively, they parametrize curves that allow a map to P1 with some specified ramification profile over two points. They are known to be tautological classes, but in general there is no known expression in terms of standard tautological classes. In this paper, we compute the intersection numbers of those DR-cycles with any monomials ...
متن کاملMonitoring Tropical Forest Fires Using Predictive Modeling for Rare Classes
This paper presents a new predictive modeling framework designed to learn classification models from imperfectly labeled samples, in the absence of expertannotated training samples, for identifying rare classes. Our results show that, under some reasonable assumptions, the classifiers trained from imperfectly labeled training data using this approach have performance comparable to the models tr...
متن کاملIntersecting Psi-classes on Tropical M 0,n
We apply the tropical intersection theory developed by L. Allermann and J. Rau to compute intersection products of tropical Psi-classes on the moduli space of rational tropical curves. We show that in the case of zero-dimensional (stable) intersections, the resulting numbers agree with the intersection numbers of Psi-classes on the moduli space of n-marked rational curves computed in algebraic ...
متن کاملResonances from J / Ψ and Ψ ′ Decays
The Institute of High Energy Physics at Beijing runs an electron-positron collider (BEPC) with a general purpose solenoidal detector, the Beijing Spectrometer (BES)[1], which is designed to study exclusive final states in ee annihilations at the center of mass energy from 3000 to 5600 MeV. In this energy range, the largest cross sections are at the J/Ψ(3097) and Ψ(3686) resonant peaks. At prese...
متن کاملSeasonal variability of size-classes of phytoplankton biomass in a sub-tropical embayment, Muscat, Sea of Oman
The contribution of three different cell size classes of picoplankton: 0.74-2 μm, nanoplankton:2–20 μm and microplankton, >20 μm of the phytoplankton population and their relationship to environmental conditions were studied over two annual cycles at one station in Bandar Khyran Bay, Sea of Oman, from May 2006 to August 2008. Nanoplankton was the most important class contributing 54.4% to tot...
