Patrick Brendan Kennedy

Patrick Brendan Kennedy (20 July 19298 June 1966) was an Irish chess champion, and professor of mathematics, notable for his work in complex analysis.

Early life, family, and personal life Kennedy was the third child of Pat Kennedy and Kit O'Sullivan, his father, a master carpenter by trade, decided instead to join the police force in 1923, many on his mother's side were blacksmiths near Castlemaine. His parents moved to Ballylongford in 1936, and secured a transfer for Kennedy to attend the North Monastery secondary school in Cork. In the same year, Kennedy also took part in the Irish Chess Championship, and won 7 games out of 7, becoming the Irish chess Champion, he has been the only Irish Chess champion to win in such a way. After this, Kennedy was described as having a falling off in the quality of his play, and lost his title at the 1950 Championship.

Kennedy's first paper was published in 1953, titled On a conjecture of Heins, which concerned a conjecture of Heins on subharmonic functions and gives positive results. That same year he was appointed as an assistant lecturer in mathematics at the University of Aberystwyth, and by 1954 he was awarded a Ph.D. by the National University of Ireland for his thesis Asymptotic Values on Integral Functions.

List of academic works Walter Hayman, a prominent British mathematician and colleague of Kennedy, describes Kennedy's work as "extremely successful in all three fields in which he wrote. "A class of integral functions bounded on certain curves". With W. K. Hayman, "On the growth of multivalent functions ". "On a theorem of Hayman concerning quasibounded functions ". "A property of bounded regular functions ". "A problem on bounded analytic functions ". "On the derivative of a function of bounded characteristic". With J. B. Twomey, "Some properties of bounded univalent functions and related classes of functions".

Fourier series "Fourier series with gaps". "Fourier series with gaps. II". "Remark on a theorem of Zygmund". "On the coefficients in certain Fourier series". "A remark on continuity conditions". "Note on Fourier series with Hadamard gaps".

Tauberian theorems "Integrability theorems for power series". " A note on uniformly distributed sequences ". "General integrability theorems for power series". With P. Sziisz, " On a bounded increasing power series". "On a theorem of Sziisz".
