The Riemann xi-function is an entire function of order one and its zeroes coincide with non-trivial zeroes of the Riemann zeta-function which lie in the critical strip. The Riemann hypothesis asserts that all zeroes of the Riemann xi-function lie on the critical line. ... Moreover, if the Riemann hypothesis is fulfilled, then all zeroes of derivatives of the Riemann xi-function lie on the critical line. ...
The Archeops experiment aimed at measuring the cosmic background emitted just after the Big Bang. The study of this radiation is essential to obtain precise information on the evolution of the Universe: density, Hubble constant, age of the Universe.. To achieve this goal, measurements have been done with devices cooled down at 100mK temperature placed at the focus of a warm telescope. ... 28960 visitors . ...
