Divided Differences and Combinatorial Identities
Studies in Applied Mathematics, 1991We present an algebraic theory of divided differences which includes confluent differences, interpolation formulas, Liebniz's rule, the chain rule, and Lagrange inversion. Our approach uses only basic linear algebra. We also show that the general results about divided differences yield interesting combinatorial identities when we consider some suitable

Root finding by divided differences
Numerische Mathematik, 1981A recursive method is presented for computing a simple zero of an analytic functionf from information contained in a table of divided differences of its reciprocalh=1/f. A good deal of flexibility is permitted in the choice of ordinate and derivative values, and in the choice of the number of previous points upon which to base the next estimate of the ...

Functionals of exponential Brownian motion and divided differences [PDF]
We provide a surprising new application of classical approximation theory to a fundamental asset-pricing model of mathematical finance. Specifically, we calculate an analytic value for the correlation coefficient between exponential Brownian motion and ...

Interlacing zeros and divided differences
Russian Mathematical Surveys, 2004The communication under review deals with the construction of sequences which alternate or preserve its sign. Two theorems generalize well known facts as that stated for polynomials with real simple zeros for which the signs of the critical values alternate. Let \(H=\{h_1,\dots ,h_n\} \) be a complete Chebyshev system on the interval \(I\), and let \(X=

A Leibniz Formula for Multivariate Divided Differences
SIAM Journal on Numerical Analysis, 2003In this paper, the algebraic background of the Leibniz formula is explored, showing the formula to be equivalent to the Opitz formula [\textit{G. Opitz}, Z. Angew. Math. Mech. 44, Sonderheft, T52--T54 (1964; Zbl 0196.48801)] that gives the divided difference table of any polynomial as the result of applying that polynomial to a certain matrix. This, in

Dividing on a Different Schedule
Science's STKE, 2006Some multinucleated cells progress through the cell cycle synchronously, and the linear progression occurs by regulated degradation of cyclins, just as in mononucleated cells. However, there are other examples where the nuclei undergo asynchronous divisions. Gladfelter et al.

Interpolation and divided differences
2002Abstract The problem that we consider in this chapter is the following: let f be a function which we assume to be continuous on the interval [a, b] and let xO, xl,... , xn be n + 1 pairwise distinct points given in the interval [a, b].

A functional equation related to divided differences
Lithuanian Mathematical Journal, 1977where [~(z); z~: . . 9 ~m] denote the m-th-order divided difference [i] of the function o~i:)~SIE and ao, al, ., an are complex constants. The operator (i) is defined for those functions o~(--)~=S(E) which do not assume the value infinity at the points ~, ~2, ~nIt is obviously linear 9 We call it the n-th order linear divided-difference operator. Let U(

‘Differences that Divide and Bind’
1998The title of this chapter is the title of a 1942 essay in Time and Tide by Rebecca West.2 Like so many British women writers, her inspiration to find meaning in a second world war began with the losses of World War I. Their painful memories were often similar, and not just because so many lost loved ones.
