Giuseppe Vitali (Ravenna, 26 d'agost de 1875 - Bolonya, 29 de febrer de 1932) va ser un matemàtic italià.

Vida i obra

Fill d'una família humil de ferroviaris,[1] el seu pare va ser destinat a Lecco, quan ell encara era a l'escola. Va acabar les seus estudis secundaris a Ravenna vivint a casa d'un oncle.[2] El curs 1895 va freqüentar els cursos de matemàtiques de la universitat de Bolonya, i l'any següent va obtenir una beca per la Scuola Normale Superiore de Pisa, en la qual es va graduar el 1899. Després d'un any com assistent d'Ulisse Dini a Pisa, va ser professor de matemàtiques de secundària successivament a Voghera i a Gènova fins al 1922.[3]

El 1923 va ser nomenat professor d'anàlisi matemàtica a la universitat de Mòdena.[4] A finals de 1926, un ictus el va deixar paralitzat de la part dreta del seu cos, però tot i així va poder seguir amb la seva activitat científica.[5] El 1930 va passar a la càtedra de Bolonya, però el 1932, mentre passejava amb el seu col·lega Ettore Bortolotti, va sofrir un nou atac i va caure fulminat.[6]

En morir va deixar inacabat un tractat titulat Moderna teoria delle funzioni di variabile reale que va ser acabat i publicat per Giovanni Sansone (1935) qui, a més, li va afegir un segon volum.

La major part de l'obra de Vitali està lligada a l'anàlisi real, havent enunciat un bon nombre de teoremes que porten el seu nom, sobre convergència, continuïtat i cobertura de les funcions reals.[7] També se li deu el descobriment del primer conjunt de nombres reals no mesurable: el conjunt de Vitali.

Layer of gases surrounding the planet Uranus Uranus by Voyager 2 The atmosphere of Uranus is composed primarily of hydrogen and helium. At depth it is significantly enriched in volatiles (dubbed ices) such as water, ammonia and methane. The opposite is true for the upper atmosphere, which contains very few gases heavier than hydrogen and helium due to its low temperature. Uranus's atmosphere is the coldest of all the planets, with its temperature reaching as low as 49 K.[1] The U...
