Positivity Problems for Low-Order Linear Recurrence Sequences

, 2013
We consider two decision problems for linear recurrence sequences (LRS) over the integers, namely the Positivity Problem (are all terms of a given LRS positive?) and the Ultimate Positivity Problem} (are all but finitely many terms of a given LRS ...

An Investigation into the Interpretation of Pi (π) as the Arithmetic Mean of the Golden Ratio (ϕ) and the Feigenbaum Constant (δ)

Chaos and Fractals
This study comprehensively examines the numerical proximity of the arithmetic mean of the golden ratio (ϕ) and the Feigenbaum constant (δ) to the number π, the theoretical mechanisms underlying this relationship, and its epistemological value.

On non-conservative perturbations of three-dimensional integrable systems [PDF]

Известия высших учебных заведений: Прикладная нелинейная динамика
At present, non-conservative perturbations of two-dimensional nonlinear Hamiltonian systems have been studied quite fully. The purpose of the study is to generalize this theory to the three-dimensional case, when the unperturbed system is nonlinear ...

On the complexity of algebraic number I. Expansions in integer bases

, 2005
Let $b \ge 2$ be an integer. We prove that the $b$-adic expansion of every irrational algebraic number cannot have low complexity. Furthermore, we establish that irrational morphic numbers are transcendental, for a wide class of morphisms. In particular,

Transcendental Numbers [PDF]

The numbers e and π are transcendental numbers, meaning each of them are not the root of any polynomial with rational coefficients. We prove that e and π are transcendental numbers. The original proofs use the Fundamental Theorem of Symmetric Polynomials

Specific Features of Polynomials in Several Examples

Axioms
This paper considers polynomial characteristics useful for a better understanding of the behaviour of these functions. Taylor series for the polynomials are described by the items with even and odd derivatives and powered changes in the argument, which ...
