Quantum Query Complexity and Span Programs from Pre-Geometry

Justin Roy Cox, Neil Epstein, Zhirui Hu +2

Span programs provide a general method for designing quantum query algorithms, and for Boolean coordinate queries their optimum cost agrees with the general adversary bound. We dev…

Rings where a non-nilpotent sum of units is a unit

Neil Epstein, Jay Shapiro

A ring is *unit-additive* if a sum of units is always either a unit or nilpotent. For example, and are unit-additive, but is not. We prove a wide-ra…

Mittag-Leffler modules and variants on intersection flatness

Rankeya Datta, Neil Epstein, Kevin Tucker

We systematically study the intersection flatness and Ohm-Rush properties for modules over a commutative ring, drawing inspiration from the work of Ohm and Rush and of Hochster and…

Rings that are Egyptian with respect to a multiplicative set

Neil Epstein

The notion of an \emph{Egyptian} integral domain (where every fraction can be written as a sum of unit fractions with denominators from ) is extended here to the notion that…

Egyptian integral domains

Neil Epstein

The notion of an Egyptian domain (where the analogue of Egyptian fractions works appropriately), first explored by Guerrieri-Loper-Oman, is extended to the more general notions of…

On posets, monomial ideals, Gorenstein ideals and their combinatorics

Geir Agnarsson, Neil Epstein

In this article we first compare the set of elements in the socle of an ideal of a polynomial algebra over a field that are not in the ideal itself and Maca…
