Question: The standard convergence test for infinite series was named after a French mathematician and physicist who was born on what day?

Context paragraphs:
Kolmogorov's three-series theorem: In probability theory, Kolmogorov's Three-Series Theorem, named after Andrey Kolmogorov, gives a criterion for the almost sure convergence of an infinite series of random variables in terms of the convergence of three different series involving properties of their probability distributions. Kolmogorov's three-series theorem, combined with Kronecker's lemma, can be used to give a relatively easy proof of the Strong Law of Large Numbers.

Integral test for convergence: In mathematics, the integral test for convergence is a method used to test infinite series of non-negative terms for convergence.  It was developed by Colin Maclaurin and Augustin-Louis Cauchy and is sometimes known as the Maclaurin–Cauchy test.

Root test: In mathematics, the root test is a criterion for the convergence (a convergence test) of an infinite series.  It depends on the quantity

Cauchy's convergence test: The Cauchy convergence test is a method used to test infinite series for convergence.  It relies on bounding sums of terms in the series.  This convergence criterion is named after Augustin-Louis Cauchy who published it in his textbook Cours d'Analyse 1821.

Augustin-Louis Cauchy: Baron Augustin-Louis Cauchy FRS FRSE (] ; 21 August 1789 – 23 May 1857) was a French mathematician and physicist who made pioneering contributions to analysis.  He was one of the first to state and prove theorems of calculus rigorously, rejecting the heuristic principle of the generality of algebra of earlier authors.  He almost singlehandedly founded complex analysis and the study of permutation groups in abstract algebra.  A profound mathematician, Cauchy had a great influence over his contemporaries and successors.  His writings range widely in mathematics and mathematical physics.

Euler's continued fraction formula: In the analytic theory of continued fractions, Euler's continued fraction formula is an identity connecting a certain very general infinite series with an infinite continued fraction.  First published in 1748, it was at first regarded as a simple identity connecting a finite sum with a finite continued fraction in such a way that the extension to the infinite case was immediately apparent.  Today it is more fully appreciated as a useful tool in analytic attacks on the general convergence problem for infinite continued fractions with complex elements.

Convergence tests: In mathematics, convergence tests are methods of testing for the convergence, conditional convergence, absolute convergence, interval of convergence or divergence of an infinite series formula_1.

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.

Abel's test: In mathematics, Abel's test (also known as Abel's criterion) is a method of testing for the convergence of an infinite series.  The test is named after mathematician Niels Henrik Abel.  There are two slightly different versions of Abel's test – one is used with series of real numbers, and the other is used with power series in complex analysis.  Abel's uniform convergence test is a criterion for the uniform convergence of a series of functions dependent on parameters.

Direct comparison test: In mathematics, the comparison test, sometimes called the direct comparison test to distinguish it from similar related tests (especially the limit comparison test), provides a way of deducing the convergence or divergence of an infinite series or an improper integral.  In both cases, the test works by comparing the given series or integral to one whose convergence properties are known.
