Tamari lattices and noncrossing partitions in type B and beyond
Hugh Thomas
The usual, or type A_n, Tamari lattice is a partial order on T_n^A, the triangulations of an (n+3)-gon. We define a partial order on T_n^B, the set of centrally symmetric triangula…
Cycles representing the Todd class of a toric variety
James Pommersheim, Hugh Thomas
In this paper, we describe a way to construct cycles which represent the Todd class of a toric variety. Given a lattice with an inner product we assign a rational number m(s) to ea…
Cycle-level intersection theory for toric varieties
Hugh Thomas
This paper addresses the problem of constructing a cycle-level intersection theory for toric varieties. We show that by making one global choice, we can determine a cycle represent…
The number of terms in the permanent and the determinant of a generic circulant matrix
Hugh Thomas
Let A=(a_(ij)) be the generic n by n circulant matrix given by a_(ij)=x_(i+j), with subscripts on x interpreted mod n. Define d(n) (resp. p(n)) to be the number of terms in the det…
