Tonelli is a surname, and may refer to:


Annalena Tonelli Italian lawyer and activist

Annalena Tonelli was an Italian lawyer and social activist. She worked for 33 years in East Africa, where she focused on tuberculosis and HIV/AIDS prevention and treatment, campaigns for eradication of female genital mutilation, and special schools for hearing-impaired, blind and disabled children. In June 2003, Tonelli was awarded the Nansen Refugee Award, which is given annually by the UNHCR to recognize outstanding service to the cause of refugees. In October 2003, she was killed inside her hospital by two gunmen. Her murder remains unsolved.

Gilles Tonelli is a Monegasque engineer, diplomat and politician.

John Tonelli Canadian ice hockey player

John A. Tonelli is a Canadian retired professional ice hockey forward. He was a four-time Stanley Cup champion with the New York Islanders, and also played with the Calgary Flames, Los Angeles Kings, Chicago Blackhawks, and the Quebec Nordiques of the National Hockey League.



In mathematics, Tonelli's theorem in functional analysis is a fundamental result on the weak lower semicontinuity of nonlinear functionals on Lp spaces. As such, it has major implications for functional analysis and the calculus of variations. Roughly, it shows that weak lower semicontinuity for integral functionals is equivalent to convexity of the integral kernel. The result is attributed to the Italian mathematician Leonida Tonelli.

The Tonelli–Shanks algorithm is used in modular arithmetic to solve for r in a congruence of the form r2n, where p is a prime: that is, to find a square root of n modulo p.

In mathematics, the Tonelli–Hobson test gives sufficient criteria for a function ƒ on R2 to be an integrable function. It is often used to establish that Fubini's theorem may be applied to ƒ. It is named for Leonida Tonelli and E. W. Hobson.

In mathematical analysis Fubini's theorem, introduced by Guido Fubini in 1907, is a result that gives conditions under which it is possible to compute a double integral by using iterated integral. One may switch the order of integration if the double integral yields a finite answer when the integrand is replaced by its absolute value.

Little Italy, Manhattan Neighborhood in Manhattan in New York City

Little Italy is a neighborhood in Lower Manhattan, New York City, once known for its large population of Italian Americans. Today the neighborhood consists of only a few Italian stores and restaurants. It is bounded on the west by Tribeca and Soho, on the south by Chinatown, on the east by the Bowery and Lower East Side, and on the north by Nolita.

Cesare ArzelĂ  Italian mathematician

Cesare Arzelà was an Italian mathematician who taught at the University of Bologna and is recognized for his contributions in the theory of functions, particularly for his characterization of sequences of continuous functions, generalizing the one given earlier by Giulio Ascoli in the Arzelà-Ascoli theorem.

In measure theory, an area of mathematics, Egorov's theorem establishes a condition for the uniform convergence of a pointwise convergent sequence of measurable functions. It is also named Severini–Egoroff theorem or Severini–Egorov theorem, after Carlo Severini, an Italian mathematician, and Dmitri Egorov, a Russian physicist and geometer, who published independent proofs respectively in 1910 and 1911.
