Albert Ingham
From Wikipedia, the free encyclopedia
Albert Edward Ingham (3 April 1900–6 September 1967) was an English mathematician.
Ingham was born in Northampton. He obtained his Ph.D., which was supervised by John Edensor Littlewood, from the University of Cambridge. He supervised the Ph.D.s of Wolfgang Fuchs and Christopher Hooley. Ingham died in Chamonix, France.
Ingham proved[1] that if
for some positive constant c, then
for any θ > (1+4c)/(2+4c). Here ζ denotes the Riemann zeta function and π the prime counting function.
Using the best published value for c at the time, an immediate consequence of his result was that
- gn < pn5/8,
where pn the n-th prime number and gn = pn+1 − pn denotes the n-th prime gap.
