INSTRUÇÃO PÚBLICA, SABER ELEMENTAR E CURRÍCULO: REFLEXÕES A PARTIR DA OBRA CONDORCET
No full textCondorcet is a author linked to the history of the public instruction and the formation ofthe republican citizen. The present text analyzes the conception of elementaryknowledge in its work as a base to argue the school curriculum in a ethical and politicalperspective. From a inicial presentation of his pedagogical ideas it is showed theelementary knowledge conception as a “key for all posterior knowledge”. One revealsthat the public instruction in its articulation with the epistemical and juridicaldimensions is essencial to his liberal conception of citizenship.Condorcet é um autor ligado à história da instrução pública e da formação docidadão republicano. O presente texto analisa a concepção de saber elementar em suaobra como um eixo para se discutir o currículo numa perspectiva ético-política. A partirde uma contextualização da obra pedagógica do autor, discute-se a sua concepção desaber elementar, destacando o seu caráter estratégico de “chave para todos os saberesposteriores”. Mostra-se que a instrução pública articular o epistêmico e o jurídico noprocesso de decisão sobre o que se chama de currículo escolar

A MEMÓRIA COMO UMA OUTRA PERSPECTIVA NA “VIRADA TESTEMUNHAL E DECOLONIAL DO SABER HISTÓRICO”, DE MÁRCIO SELIGMANN-SILVA
No full textPublished in 2022, A virada testemunhal e decolonial do saber histórico, a book by Márcio Seligmann-Silva, brings together twelve texts, some already published in scientific journals and now prepared for a chapter, some unpublished, which proposes to present another perspective on historical knowledge. This perspective, as proposed by the author himself, is a vision that comes from the “testimonial and decolonial turn” of history, and to contribute to this knowledge, the theorist presents Memory as another possibility of understanding the past. Composing his argument, the theory brings to our reflection thinkers from philosophy, history, literature, as well as considerations on the category and its various facets which we propose to present in this review.RESUMO: Publicado em 2022, A virada testemunhal e decolonial do saber histórico, livro de Márcio Seligmann-Silva reúne doze textos, alguns já publicados em revistas científicas e agora elaborados para capítulo, alguns inéditos, os quais se propõe a apresentar uma outra perspectiva ao saber histórico. Essa perspectiva, conforme propõe o próprio autor, se trata de uma visão que é oriunda da “virada testemunhal e decolonial” da história, e para a contribuição desse saber, o teórico apresenta a Memória como mais uma possibilidade de compreensão do passado. Compondo o seu argumento, o teórico traz para a nossa reflexão pensadores da filosofia, história, literatura, bem como ponderações sobre a categoria e suas diversas facetas as quais nos propomos a apresentar nesta resenha
The -Neumann operator on Lipschitz -pseudoconvex domains
No full textsummary:On a bounded -pseudoconvex domain in with a Lipschitz boundary, we prove that the -Neumann operator satisfies a subelliptic -estimate on and can be extended as a bounded operator from Sobolev -spaces to Sobolev -spaces
Compactness of the canonical solution operator on Lipschitz q-pseudoconvex boundaries
No full textLet Ω ⊂ ℂn be a bounded Lipschitz q-pseudoconvex domain that admit good weight functions. We shall prove that the canonical solution operator for the the ∂¯-equation is compact on the boundary of Ω and is bounded in the Sobolev space Wkr,s(Ω) for some values of k. Moreover, we show that the Bergman projection and the ∂¯-Neumann operator are bounded in the Sobolev space Wkr,s(Ω) for some values of k. If Ω is smooth, we shall give sufficient conditions for compactness of the ∂¯-Neumann operator.Mathematic

Control of chaos in the burke-shaw system of fractal-fractional order in the sense of Caputo-Fabrizio
No full textFor the Burke-Shaw system, we propose a fractal-fractional order in the sense of the Caputo-Fabrizio derivative. The proposed system is solved by utilizing the fractal-fractional derivative operator with an exponential decay kernel. Time-fractional Caputo-Fabrizio fractal fractional derivatives are applied to the Burke-Shaw-type nonlinear chaotic systems.Based on fixed point theory, it has been demonstrated that a fractal-fractional-order model under the Caputo-Fabrizio operator exists and is unique. Using a numerical power series method, we solve the fractional Burke-Shaw model. Using Newton’s interpolation polynomial, we solve the equation numerically by implementing a novel numerical scheme based on an efficient polynomial
