On Third-Order Linear Recurrent Functions
Discrete Dynamics in Nature and Society, 2019 A function ψ:R→R is said to be a Tribonacci function with period p if ψ(x+3p)=ψ(x+2p)+ψ(x+p)+ψ(x), for all x∈R. In this paper, we present some properties on the Tribonacci functions with period p. We show that if ψ is a Tribonacci function with period p,

Recurrence Relations for Orthogonal Functions [PDF]
, 2020 When µ is a finite (positive) Borel measure with infinite support on T or R (with suitable restrictions), positive definite functionals M (and thereby positive definite inner products) are defined through M(f)=∫_{-π..π}f(e^{it})dµ(t) in the circle-disk situation, and M(f)=∑_{-∞..∞}f(t)dµ(t) in the line-plane situation.

Recurrent identities for two special functions of hypergeometric type
Вестник Самарского университета: Естественнонаучная серия, 2023 The article presents conclusions and proofs of Gauss-type identities for two known hypergeometric type functions. For the derivation and justification of formulas, the representation of functions in the form of a series is used, as well as an integral ...

Eigenpairs for the Analysis of Complete Lyapunov Functions
Complexity, 2022 A complete Lyapunov function describes the qualitative behaviour of a dynamical system: the areas where the orbital derivative vanishes and where it is strictly negative characterise the chain recurrent set and the gradient-like flow, respectively ...

Recurrence techniques for the calculation of bessel functions [PDF]
Preprints of papers presented at the 14th national meeting of the Association for Computing Machinery on - ACM '59, 1959 where Fv(x) may be either J,(x) or Y,(x). If one is given Y,(x) and Yv+?(x) then Eq. (1) may be used to generate the functions Yv+,(x). For ? >> (x/2) the function Y,(x) increases extremely rapidly with increasing order, i.e., Y,(x) -(2,u/x) and the functions Y,+n(x) calculated from Eq. (1) yield good accuracy for large n. However, if one is given JA(x)

CoRR, 2019 Despite recent successes in Reinforcement Learning, value-based methods often suffer from high variance hindering performance. In this paper, we illustrate this in a continuous control setting where state of the art methods perform poorly whenever sensor noise is introduced.
