We shall use the quantities and notation stated in [1]. The Petrov classification (PC) [1-8] of the Weyl tensor has a great importance in general relativity, thus it is attractive to account with an efficient procedure to determine the Petrov type of an arbitrary gravitational field. Peres [9] has worked out the tensorial version of the Petrov’s matrix approach [2-4] to perform the PC. In the f...

O presente trabalho problematiza como os itinerários formativos têm se materializados no cotidiano de uma Escola Estadual Ensino Médio na Região Integração do Marajó? Objetivando compreender a materialização da oferta dos Gerson Peres. método norteador é o materialismo histórico-dialético, ainda envolveu pesquisa bibliográfica. Os foram determinados pela lei nº 13.415 e sua manifesta um grande ...

For percolation on finite transitive graphs, Nachmias and Peres suggested a characterization of the critical probability based on the logarithmic derivative of the susceptibility. As a first test-case, we study their suggestion for the Erdős–Rényi random graph Gn,p, and confirm that the logarithmic derivative has the desired properties: (i) its maximizer lies inside the critical window p = 1/n+...

Considering the benefits of Quantum and Optics, if the logic gates in the quantum field and electronic structure are implemented using optical elements, then it will be benefited from advantages of Quantum and design, and these processing circuits can be used in optical computing and quantum computing, genetic processes, and other useful nanotechnology applications. In this study, we have intro...

Peres and Winkler proved a ‘censoring’ inequality for Glauber dynamics on monotone spins systems such as the Ising model. Specifically, if, starting from a constant-spin configuration, the spins are updated at some sequence of sites, then inserting another site into this sequence brings the resulting configuration closer in total variation to the stationary distribution. We show by means of sim...
