Geometric quantization and non-perturbative Poisson sigma model [PDF]

open access: yes, 2005
In this note we point out the striking relation between the conditions arising within geometric quantization and the non-perturbative Poisson sigma model.

Fast Convex Decomposition for Truthful Social Welfare Approximation [PDF]

open access: yes, 2014
Approximating the optimal social welfare while preserving truthfulness is a well studied problem in algorithmic mechanism design. Assuming that the social welfare of a given mechanism design problem can be optimized by an integer program whose ...

Anomalous D-Brane Charge in F-Theory Compactifications [PDF]

open access: yes, 2000
Tadpole cancellation in F-theory on an elliptic Calabi-Yau fourfold $X\to B_3$ demands some spacetime-filling three-branes (points in $B_3$). If moved to the discriminant surface, which supports the gauge group, and dissolved into a finite size instanton,

Integrality of the therapeutic and pharmaceutical care: a necessary debate

open access: yesRevista de Saúde Pública, 2017
The controversy surrounding the different interpretations on the integrality of therapeutic and pharmaceutical care has led to the delimitation of its scope by a law, but the issue has not been completely pacified.

Integrality of hook ratios [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We study integral ratios of hook products of quotient partitions. This question is motivated by an analogous question in number theory concerning integral factorial ratios. We prove an analogue of a theorem of Landau that already applied in the factorial

New Integrality Gap Results for the Firefighters Problem on Trees

open access: yes, 2016
The firefighter problem is NP-hard and admits a $(1-1/e)$ approximation based on rounding the canonical LP. In this paper, we first show a matching integrality gap of $(1-1/e+\epsilon)$ on the canonical LP.

On Column-restricted and Priority Covering Integer Programs

open access: yes, 2010
In a column-restricted covering integer program (CCIP), all the non-zero entries of any column of the constraint matrix are equal. Such programs capture capacitated versions of covering problems.

Geography, public administration and governance

open access: yesBelgeo, 2000
Attention is directed to a number of principles that possibly can guide the on-going debates on governmental and administrative reform. The most important principles are the integrality of political decision-making at each self-governmental tier and ...
