Derivations of Lotka-Volterra algebras

São Paulo Journal of Mathematical Sciences, 2018
A commutative (not necessary associative) algebra \(A\) over a field \(F\) with characteristic not two is called a Lotka-Volterra algebra if it admits a so-called natural basis \(\mathcal{B} = \{e_1,\dots, e_n\}\), such that \(e_i e_j = \alpha_{ij} e_i + \alpha_{ji} e_j\) with \(\alpha_{ij}\in F\) satisfying \(a_{ii} = 1/2\), and \(\alpha_{ij ...

Supervised inductive learning with Lotka–Volterra derived models

Knowledge and Information Systems, 2008
We present a classification algorithm built on our adaptation of the Generalized Lotka–Volterra model, well-known in mathematical ecology. The training algorithm itself consists only of computing several scalars, per each training vector, using a single global user parameter and then solving a linear system of equations.

Accurate similarity transformation derived from the discrete Lotka–Volterra system for bidiagonal singular values

Calcolo, 2013
The discrete Lotka-Volterra (dLV) system describes the predator-prey evolution of \(2m-1\) different species \(u_k\), \(k=1,\dots,2m-1\). The time discretisation \(\delta^{(n)}\) may vary with time \(n\). A bidiagonal matrix \(B\in\mathbb{R}^{m\times m}\) defines the initial conditions for \(n=0\). The continuous system results as \(\delta^{(n)}\to0\).

Dynamical Behaviours of a Lotka Volterra Model with Katugampola Fractional Derivative

The interdisciplinary journal of Discontinuity, Nonlinearity, and Complexity, 2019
In this paper, we study the dynamical behaviours of a very special type of delay differential equation known as Lotka Volterra model (predator-prey model) via Katugampola fractional derivative. The existence and uniqueness results are obtained using the Krasnoselskii’s fixed point theorem.
