Refinements of spectral resolutions and modelling of operators in II1 factors
(Theta Foundation, 2008-03)
We study refinements between spectral resolutions in an arbitrary II1 factor M and obtain diffuse (maximal) refinements of spectral resolutions. We construct models of operators with respect to diffuse spectral resolutions. ...

Improved analysis of a max-cut algorithm based on spectral partitioning
(SIAM, 2015)
Trevisan [SIAM J. Comput., 41 (2012), pp. 1769-1786] presented an algorithm for Max-Cut based on spectral partitioning techniques. This is the first algorithm for Max-Cut with an approximation guarantee strictly larger ...
Estudo da resposta espectral de alvos urbanos com espectroscopia de reflectância e imagens de alta resolução espacial
(Universidade Federal de Santa MariaBrasilGeografiaUFSMPrograma de Pós-Graduação em GeografiaCentro de Ciências Naturais e Exatas, 2014-12-10)
Urban areas are composed with diverse set of materials arranged in a complex way
by man for its survival. Remote sensing is the tool with potential for obtain spectral
data of urban materials and their conditions. This ...
A comparison of spectral macroalgae taxa separability methods using an extensive spectral library
(Elsevier B.V., 2017-09)
Remote sensing is one the most promising approaches to coastal area cartography, including mapping algae forests. After discrimination of algal communities from other benthic habitats, next step is species discrimination ...
SPECTRAL PROPERTIES OF A NON SELFADJOINT SYSTEM OF DIFFERENTIAL EQUATIONS WITH A SPECTRAL PARAMETER IN THE BOUNDARY CONDITION
(Universidad Católica del Norte, Departamento de Matemáticas, 2005)
On a formula for the spectral flow and its applications
(WILEY-V C H VERLAG GMBH, 2010)
We consider a continuous path of bounded symmetric Fredholm bilinear forms with arbitrary endpoints on a real Hilbert space, and we prove a formula that gives the spectral flow of the path in terms of the spectral flow of ...
