Subword complexes via triangulations of root polytopes [PDF]

open access: yes, 2017
Subword complexes are simplicial complexes introduced by Knutson and Miller to illustrate the combinatorics of Schubert polynomials and determinantal ideals. They proved that any subword complex is homeomorphic to a ball or a sphere and asked about their

Gauged sigma-models with nonclosed 3-form and twisted Jacobi structures

open access: yesJournal of High Energy Physics, 2020
We study aspects of two-dimensional nonlinear sigma models with Wess-Zumino term corresponding to a nonclosed 3-form, which may arise upon dimensional reduction in the target space. Our goal in this paper is twofold.

A survey of parallel execution strategies for transitive closure and logic programs [PDF]

open access: yes, 1993
An important feature of database technology of the nineties is the use of parallelism for speeding up the execution of complex queries. This technology is being tested in several experimental database architectures and a few commercial systems for ...

Algebraic optimization of recursive queries [PDF]

open access: yes, 1992
Over the past few years, much attention has been paid to deductive databases. They offer a logic-based interface, and allow formulation of complex recursive queries.

Internal representation of hierarchical sequences involves the default network

open access: yesBMC Neuroscience, 2010
Background The default network is a set of brain regions that exhibit a reduction in BOLD response during attention-demanding cognitive tasks, and distinctive patterns of functional connectivity that typically include anti-correlations with a fronto ...
