Multiplication of sequences with zero autocorrelation [PDF]
Australas. J Comb., 2020 This paper may be regarded as a continuation of the paper by the authors [On sequences with zero autocorrelation, Des. Codes Cryptography 4, No. 4, 327-340 (1994; Zbl 0808.05021)]. Main results of the present paper may be stated as follows: A set of near normal sequences of length \(n= 4m+ 1\) is defined as a quadruple of \((- 1,0,1)\)-sequences of ...

On cross numbers of minimal zero sequences [PDF]
Australas. J Comb., 2020 Let \(G\) be an (additively written) finite abelian group. Let us say that \(S=\{g_1,\dots,g_t\}\) is a minimal zero sequence if \(\sum_{1\leq i\leq t}g_i=0\) and there is not a proper subset \(I\subset \{1,2,\dots,t\}\) for which \(\sum_{i\in I}g_i=0\). The cross number \(k(S)\) is defined by \(k(S)=\sum^t_{i=1} [\text{ord } g_i]^{-1}\).

Zeros of polynomials embedded in an orthogonal sequence
Numerical Algorithms, 2010Let $\{x_{k,n}\}_{k=1}^n$ and $\{x_{k,n+1}\}_{k=1}^{n+1}$ , n????, be two given sets of real distinct points with x 1,n?+?1? ?0, which are chosen arbitrarily, that define p n?+?2 via the three term recurrence relation $$ p_{n+2}(x)=(x-b_{n+1})p_{n+1}(x)-\lambda_{n+1}p_n(x). $$

On integer-valued zero autocorrelation sequences
2013 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference, 2013A systematic way to construct Integer-valued zero autocorrelation sequences is proposed. This method only uses fundamental theorems of discrete Fourier transform(DFT) and some number theories.

Generalized zero-sequence and anti-zero-sequence performance of induction machines
Archiv für Elektrotechnik, 1981The present paper derives a new general zero-sequence steady state ladder equivalent circuit of threephase induction machines where zero-sequence currents can simultaneously flow in both the stator and rotor windings. A general expression for the zero-sequence torque is also derived.

Search for sequences with zero autocorrelation
1988It exists sequences of length N of constant amplitude and zero autocorrelation over 2n symbols, provided that each sequence be preceeded by n symbols and followed by n other symbols. Methods for obtaining these N + 2n symbols are proposed and examples are given.

The convergence to zero of Gaussian sequences
Mathematical Notes of the Academy of Sciences of the USSR, 1977Conditions for Gaussian sequences to converge to zero with unit probability are examined. A comparison theorem is proved, on the basis of which sufficient conditions are derived for the convergence to zero of Gaussian sequences, including, in particular, the previously known ones.

Overconvergence and Zeros of sequences of rational functions
Approximation Theory and its Applications, 1993Summary: We consider sequences of rational functions with a bounded number of free poles converging uniformly with a maximum geometric rate to a holomorphic function on a regular set, and we examine the limiting distribution of the zeros and its relations with the phenomenon of overconvergence. Our results further extend the well known classical theory

Zero sequences for bergman spaces
Complex Variables, Theory and Application: An International Journal, 1996Let Z be a sequence of points in the unit disk. For a variety of analytic function spaces, it is shown that the properties of the function completely determine whether Z is a zero sequence for the given space. For example, if A -n= {f analytic in D f(z)(1-|z|2)n then Z is a zero sequence for A −n if and only if kZ(z)−nlog[1/(1-|z|2)] has a harmonic ...

We consider here a sequence of chemically homogeneous models in complete (mechanical and thermal) equilibrium with central hydrogen burning. All of them are composed of the same hydrogen-rich mixture, while the stellar mass M varies from model to model along the sequence.
