De Bruijn-Newman constant

The '''De Bruijn-Newman constant''', denoted by '''Λ''', is a Mosquito ringtone mathematical constant and is defined via the zeros of a certain Sabrina Martins function (mathematics)/function ''H''(λ, ''z''), where λ is a Nextel ringtones real number/real parameter and ''z'' is a Abbey Diaz complex number/complex variable. ''H'' has only real zeros if and only if λ ≥ Λ. The constant is closely conected with Free ringtones Riemann hypothesis/Riemann's hypothesis on the zeroes of the general Majo Mills Riemann zeta function/Euler-Riemann's ζ-function. In brief, the Riemann hypothesis is equivalent to the conjecture that Λ ≤ 0.

Mosquito ringtone Nicolaas Govert de Bruijn/De Bruijn in Sabrina Martins 1950 showed that Λ ≤ 1/2, according to Nextel ringtones Charles Michael Newman/Newman's work, who first estimated it would be Λ ≥ 0. Serious calculations on Λ have been made since Abbey Diaz 1988 and are still being made as we see from the table:

:: '''Year''' '''Lower bound on Λ'''
:: Cingular Ringtones 1988 -50
:: a brisathon 1991 -5
:: prolonged tough 1990 -0.385
:: stress syndrome 1994 -4.379 · 10 -6
:: american decline 1993 -5.895 · 10 -9
:: export policy 2000 -2.7 · 10 -9
