The Zero-Age Main Sequence

2012
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.

Zeros of linear recurrence sequences

Publicationes Mathematicae Debrecen, 2000
A sequence \(U=\{u_n\}_{n\in \mathbb Z}\) of complex numbers is called a linear recurrence sequence if it satisfies a relation \(u_n=c_1u_{n-1}+\dots+c_t u_{n-t}\) with \(c_i\in \mathbb C\) and \(c_t\neq 0\). There is only one such relation for which \(t\) is minimal.

Zero sequences for bergman spaces

Complex Variables, Theory and Application: An International Journal, 1996
Let 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 ...

Ternary sequence with zero correlation

Proceedings of the IEEE, 1967
A method of generating ternary sequences with zero cyclic correlation except for the spike for zero lag is described. The sequences are of length given by (3n-1)/2 where n is odd. A method of generating uncorrelated sequences derived from the ternary sequence modified by a Hadamard matrix is indicated.
