چکیده

We study the average number of intersecting points of a given curve with random hyperplanes in an n-dimensional Euclidean space. As noticed by A. Edelman and E. Kostlan this problem is closely linked to nding the average number of real zeros of random polynomials. They show that a real polynomial of degree n has in average 2 log n + O(1) real zeros (M. Kac's theorem). This result leads us to the following question: given a real sequence (k) k2N , to study the average 1 N P N?1 n=0 (fn); where (fn) is the number of real zeros of fn(X) = 0 + 1 X + + nX n. Theoretical results are given for the Thue-Morse polynomials as well as numerical evidence for other polynomials.

On the real roots of generalized Thue-Morse polynomials

In this article we investigate real roots of real polynomials. By results of M. Kac 8, 9, 10] we know that a polynomial of degree n has in average 2 log n real zeros. See also results of Edelman and Kostlan 5] on the same subject. Some 10 years later Erdds and OOord 7] proved that the mean number of real roots of a random polynomial of degree n with coeecients 1 is again 2 log n: This leads us ...

Acoustic Wave propagation through multilayer Thue-Morse structures containing two, three and four materials of Cu, Al, MgO and Pb

In this paper, the acoustic wave propagation in multilayer Thue-Morse structures has theoretically been studied. The composing layers were assumed do be Cu, Al, Mgo and Pb materials. Two, three or four different materials have been used in a typical structure. By using a perpendicular incident acoustic wave, the transmission coefficient was calculated and then by its old, the frequency gaps was...

Domain of attraction of normal law and zeros of random polynomials

Let$ P_{n}(x)= sum_{i=0}^{n} A_{i}x^{i}$ be a random algebraicpolynomial, where $A_{0},A_{1}, cdots $ is a sequence of independent random variables belong to the domain of attraction of the normal law. Thus $A_j$'s for $j=0,1cdots $ possesses the characteristic functions $exp {-frac{1}{2}t^{2}H_{j}(t)}$, where $H_j(t)$'s are complex slowlyvarying functions.Under the assumption that there exist ...

On Sums of Powers of Zeros of Polynomials

Due to Girard’s (sometimes called Waring’s) formula the sum of the r−th power of the zeros of every one variable polynomial of degree N , PN (x), can be given explicitly in terms of the coefficients of the monic P̃N (x) polynomial. This formula is closely related to a known N − 1 variable generalization of Chebyshev’s polynomials of the first kind, T (N−1) r . The generating function of these po...
