✦ Synopsis


An infinite set of natural numbers is called a B 3 -sequence if all sums a 1 +a 2 +a 3 with a j # A and a 1 a 2 a 3 are distinct. Let A(n) be the number of positive elements n in A. P. Erdo s conjectures that every B 3 -sequence A satisfies lim inf n Γ„ A(n) n &1Γ‚3 =0. In this paper we prove that no sequence satisfying A(n)t:n 1Γ‚3 can be a B 3 -sequence. We also give other necessary conditions for a B 3 -sequence.

The equilibrium concentrations of B(OH) 3 in the coexisting phases of water and steam were measured over the temperature range 452.3 K to 643.7 K. These data were used to calculate the distribution constant K D of B(OH) 3 . Making use of Krichevskii's function, the distribution results were compared

The concept of well-hstribution with respect to weighted means was introduced for the interval [0, 1) by the author [4], [j], cf. also TICHY [7], [8] for a preparatory special case. Recently DRMOTA/TICHT [l] have generalized t h s concept to a compact metric space X. They have got first metric resul
