Variational reduced density matrix method in the doubly-occupied configuration interaction space using four-particle N-representability conditions: Application to the XXZ model of quantum magnetism
(American Institute of Physics, 2019-10-15)
This work deals with the variational determination of the two-particle reduced density matrix (2-RDM) and the energy corresponding to the ground state of N-particle systems within the doubly occupied configuration interaction ...
GBStools: A Statistical Method for Estimating Allelic Dropout in Reduced Representation Sequencing Data
(Public Library of Science, 2016-02)
Reduced representation sequencing methods such as genotyping-by-sequencing (GBS) enable low-cost measurement of genetic variation without the need for a reference genome assembly. These methods are widely used in genetic ...
Covering functors without groups
(Academic Press Inc Elsevier Science, 2009-06)
Coverings in the representation theory of algebras were introduced for the Auslander-Reiten quiver of a representation-finite algebra in [Ch. Riedtmann, Algebren, Darstellungsköcher, Überlagerungen und zurüch, Comment. ...
Nature representation in South American protected areas: country contrasts and conservation priorities
(PeerJ Inc., 2019-07)
Background. South America faces strong environmental pressures as a result of agriculture and infrastructure expansion and also of demographic growth, demanding immediate action to preserve natural assets by establishing ...
Learning network representations
(EDP Sciences, 2017-02)
In this review I present several representation learning methods, and discuss the latest advancements with emphasis in applications to network science. Representation learning is a set of techniques that has the goal of ...
Branching laws, examples and some new results
(Unión Matemática Argentina, 2018-06)
For a connected, noncompact simple matrix Lie group G so that a maximal compact subgroup K has a three dimensional simple ideal, in this note we analyze the admissibility of the restriction of irreducible square integrable ...
Some remarks on distributive semilattices
(Charles University. Faculty of Mathematics and Physics, 2013-06)
In this paper we shall give a survey of the most important characterizations of the notion of distributivity in semilattices with greatest element and we will present some new through annihilators and relative maximal ...
Aimé Bonpland's drawings of Itá Pucú, 1834, and the history of early geological representations in Argentina
(History Earth Sciences Society, 2004-01)
The early geological representations in Argentina dated from the middle of the nineteenth century when Alcide d'Orbigny, Charles Darwin, Bartholomew James Sulivan, Franz Foetterle, Auguste Bravard, Jakob Christen Heusser ...
Congruences between modular forms modulo prime powers
(Universidad Autónoma de Madrid, 2018-12-06)
Given a prime p≥5 and an abstract odd representation ρ n with coefficients modulo p n (for some n≥1 and big image, we prove the existence of a lift of ρ n to characteristic 0 whenever local lifts exist (under minor technical ...
Weight multiplicity formulas for bivariate representations of classical Lie algebras
(American Institute of Physics, 2018-08-27)
A bivariate representation of a complex simple Lie algebra is an irreducible representation whose highest weight is given by a combination of the first two fundamental weights. For a complex classical Lie algebra, we ...
