Generalized Tribonacci Hyperbolic Spinors [PDF]

In this study, we introduce the generalized Tribonacci hyperbolic spinors and properties of this new special numbers system by the generalized Tribonacci numbers, which are one of the most general form of the third-order recurrence sequences, generalized

Tribonacci Sequences With Certain Indices and Their Sums

, 2008
In this paper, we derive new recurrence relations and generating matrices for the sums of usual Tribonacci numbers and 4n subscripted Tribonacci sequences, {T-4n}, and their sums. We obtain explicit formulas and combinatorial representations for the sums

On the Brocard--Ramanujan Equation with Tribonacci and Tetranacci Numbers

It is shown that the Brocard-Ramanujan equation \(m! + 1 = u^2\) has no integer solutions when \(u\) is a Tribonacci number. This investigation is motivated by a previously published incorrect proof in the work of \textit{V. Facó} and \textit{D. Marques} [J. Integer Seq. 19, No. 4, Article 16.4.4, 7 p. (2016; Zbl 1415.11028)].
