Chern class formulas for classical-type degeneracy loci
David Anderson, William Fulton
In previous work, we employed a geometric method of Kazarian to prove Pfaffian formulas for a certain class of degeneracy loci in types B, C, and D. Here we refine that approach to…
Degeneracy Loci, Pfaffians, and Vexillary Signed Permutations in Types B, C, and D
David Anderson, William Fulton
We define a notion of vexillary signed permutation in types B, C, and D, corresponding to natural degeneracy loci for vector bundles with symmetries of those types. We show that th…
The Picard group of
William Fulton, Martin Olsson
We compute the Picard group of the moduli stack of elliptic curves and its canonical compactification over general base schemes.
On the quantum cohomology of homogeneous varieties
William Fulton
This is an expository lecture, for the Abel bicentennial (Oslo, 2002), describing some recent work on the (small) quantum cohomology ring of Grassmannians and other homogeneous var…
Eigenvalues, singular values, and Littlewood-Richardson coefficients
Sergey Fomin, William Fulton, Chi-Kwong Li +1
We characterize the relationship between the singular values of a complex Hermitian (resp., real symmetric, complex symmetric) matrix and the singular values of its off-diagonal bl…
Adjoints and Max Noether's Fundamentalsatz
William Fulton
We give an exposition of the theory of adjoints and conductors for curves on nonsingular surfaces, emphasizing the case of plane curves, for which the presentation is particularly…
