The standard convergence test for infinite series was named after a French mathematician and physicist who was born on what day?
Cauchy condensation test In mathematics, the Cauchy condensation test, named after Augustin-Louis Cauchy, is a standard convergence test for infinite series. For a non-negative, non-increasing sequence formula_1 of real numbers, the series formula_2 converges if and only if the "condensed" series formula_3 converges. Moreover, if they converge, the sum of the condensed series is no more than twice as large as the sum of the original.
Edmond Laguerre Edmond Nicolas Laguerre (April 9, 1834, Bar-le-Duc – August 14, 1886, Bar-le-Duc) was a French mathematician, a member of the Académie française (1885). His main works were in the areas of geometry and complex analysis. He also investigated orthogonal polynomials (see Laguerre polynomials). Laguerre's method is a root-finding algorithm tailored to polynomials. He laid the foundations of a geometry of oriented spheres (Laguerre geometry and Laguerre plane), including the Laguerre transformation or transformation by reciprocal directions.
