Cauchy's Continuum [PDF]

open access: yesPerspectives on Science, 2011
Cauchy's sum theorem of 1821 has been the subject of rival interpretations ever since Robinson proposed a novel reading in the 1960s. Some claim that Cauchy modified the hypothesis of his theorem in 1853 by introducing uniform convergence, whose traditional formulation requires a pair of independent variables.

Testing continuity in a Michigan (USA) river using the organic biomass of adult Ephemeroptera, Plecoptera, and Trichoptera

open access: yesJournal of Freshwater Ecology, 2022
While there is substantial support for the river continuum concept (RCC) using aquatic macroinvertebrates, nearly all of this support has come from studies using benthic specimen counts or relative biomass as the basis for comparing sites.

THE TEMPORAL CONTINUUM

open access: yesThe Review of Symbolic Logic
AbstractThe continuum has been one of the most controversial topics in mathematics since the time of the Greeks. Some mathematicians, such as Euclid and Cantor, held the position that a line is composed of points, while others, like Aristotle, Weyl, and Brouwer, argued that a line is not composed of points but rather a matrix of a continued insertion ...

Influência da relação resposta/reforço na persistência comportamental

open access: yesRevista Portuguesa de Investigação Comportamental e Social
Contexto: A Teoria do Momentum Comportamental propõe que a persistência comportamental resulta da relação estímulo-estímulo independentemente da relação resposta-estímulo.
