Čech cohomology of infinite projective spaces, flag manifolds, and related spaces
David Anderson, Matthias Franz
We compute the Čech cohomology ring of a countable product of infinite projective spaces, and that of an infinite flag manifold. The method of our first result in fact computes the…
Filtrations and recursions for Schubert modules
David Anderson
Revisiting Kraśkiewicz and Pragacz's construction of Schubert modules, we provide a new proof that their characters are equal to Schubert polynomials. The main innovation is a repr…
Toric arc schemes and -enumeration of lattice points
Dave Anderson, Aniket Shah
We introduce a natural weighted enumeration of lattice points in a polytope, and give a Brion-type formula for the corresponding generating function. The weighting has combinatoria…
Bounded and finite factorization domains
David F. Anderson, Felix Gotti
An integral domain is atomic if every nonzero nonunit factors into irreducibles. Let be an integral domain. We say that is a bounded factorization domain if it is atomic an…
On n-semiprimary Ideals and n-pseudo Valuation Domains
David F. Anderson, Ayman Badawi
In this paper, we introduce the concept of n-semiprimary ideals, n-powerful ideals, and n-powerful semiprimary ideals of commutative rings. We study these concepts and relate them…
Completely integrally closed Prufer -multiplication domains
D. D. Anderson, D. F. Anderson, M. Zafrullah
We study the effects on of assuming that the power series ring is a -domain or a PVMD. We show that a PVMD is completely integrally closed if and only if $\bigc…
