Some Positivities in Stirling Arrays with Higher Level

نویسندگان

چکیده

Abstract In this paper, we prove that the sequences of Stirling numbers first and second kind with higher level are both Pólya frequency log-concave. Then, show some polynomials related to above q -log-convex or strongly -log-convex. Furthermore, establish linear transformation 2 preserves log-convexity.

Some robust higher-level percepts for music.

We explored a range of higher-level percepts in music. Participants were asked to make two-alternative forced-choice judgments of extracts of instrumental music on various dipole categories, such as happy/sad or male/female. The consistency with which each stimulus was judged on a response category across listeners provides an indication of the extent to which the musical percept can be mapped ...

Some Remarks on the Stirling Numbers

Sdn, n-k)= L B1 (k, j) j=1 and k C+:;I). S(n, n-k) = L B(k, j) j~1 Moreover (1. 6) B1 (k, j)=B(k, k-j+ 1) (1 ~j~k). 1. The Stirling numbers SI (n, k), S (n, k) of the first and second kind Tespectively, can be defined by (1.1) n x(x+l).. .(x+n-l)-L SI(n, k)Xk k=O .and (1.2) n xn= L S(n, k)x(x~ 1).. .(x-k+ 1). k=O Also it is well known that SI (n,n-k) and S(n, n-k) are polynomials in n ~f degree...

Some Properties of Associated Stirling Numbers

Abstract In this paper, we discuss the properties of associated Stirling numbers. By means of the method of coefficients, we establish a series of identities involving associated Stirling numbers, Bernoulli numbers, harmonic numbers, and the Cauchy numbers of the first kind. In addition, we give the asymptotic expansion of certain sums involving 2-associated Stirling numbers of the second kind ...
