A graphical interface for the Gromov--Witten theory of curves
Renzo Cavalieri, Paul Johnson, Hannah Markwig +1
We explore the explicit relationship between the descendant Gromov--Witten theory of target curves, operators on Fock spaces, and tropical curve counting. We prove a classical/trop…
Lattice points and simultaneous core partitions
Paul Johnson
We observe that for a and b relatively prime, the "abacus construction" identifies the set of simultaneous (a,b)-core partitions with lattice points in a rational simplex. Furtherm…
Hurwitz numbers, ribbon graphs, and tropicalization
Paul Johnson
Double Hurwitz numbers have at least four equivalent definitions. Most naturally, they count covers of the Riemann sphere by genus g curves with certain specified ramification data…
Double Hurwitz numbers via the infinite wedge
Paul Johnson
We derive an algorithm to produce explicit formulas for certain generating functions of double Hurwitz numbers. These formulas generalize a formula of Goulden, Jackson and Vakil fo…
An IR Search for Extinguished Supernovae in Starburst Galaxies
Bruce Grossan, Earl Spillar, Robert Tripp +3
IR and Radio band observations of heavily extinguished regions in starburst galaxies suggest a very high SN rate associated with such regions. Optically measured supernova (SN) rat…
