چکیده

The Riemann hypothesis is equivalent to the Li criterion governing a sequence of real constants {λk}k=1, that are certain logarithmic derivatives of the Riemann xi function evaluated at unity. We investigate a related set of constants cn, n = 1, 2, . . ., showing in detail that the leading behaviour (1/2) ln n of λn/n is absent in cn. Additional results are presented, including a novel explicit representation of cn in terms of the Stieltjes constants γj . We conjecture as to the large-n behaviour of cn. Should this conjecture hold, validity of the Riemann hypothesis would follow.

We prove that the classical, non–periodic Toda lattice is super–integrable. In other words, we show that it possesses 2N−1 independent constants of motion, where N is the number of degrees of freedom. The main ingredient of the proof is the use of some special action–angle coordinates introduced by Moser to solve the equations of motion. Mathematics Subject Classification: 37K10, 37J35, 70H06

HCN J =8→ 7 sub-millimetre line emission produced in the circumstellar envelope around the extreme carbon star IRC+10216 has been imaged at sub-arcsecond angular resolution using the SMA. Supplemented by a detailed excitation analysis the average fractional abundance of HCN in the inner wind (. 5× 10 cm) is estimated to be about 4× 10, translating into a total HCN fractional abundance of 2× 10 ...
