On Linear Differential Equations Involving a Para-Grassmann Variable [PDF]

open access: yes, 2009
As a first step towards a theory of differential equations involving para-Grassmann variables the linear equations with constant coefficients are discussed and solutions for equations of low order are given explicitly.

Avaliação de métodos laboratoriais para estimar a digestibilidade e o valor energético de dietas para ruminantes Evaluation of laboratorial methods to estimate the digestibility and energetic value of ruminant diets

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2009
Foi avaliada a acurácia dos métodos laboratoriais para estimar a digestibilidade e o valor energético de dietas para bovinos de corte. As dietas experimentais foram isonitrogenadas e compostas por silagem de milho e 25, 40, 55 ou 70% de concentrado.

Difference Equations Compatible with Trigonometric KZ Differential Equations [PDF]

open access: yes, 2000
The trigonometric KZ equations associated with a Lie algebra $\g$ depend on a parameter $\lambda\in\h$ where $\h\subset\g$ is the Cartan subalgebra. We suggest a system of dynamical difference equations with respect to $\lambda$ compatible with the KZ ...

Dendriform equations

open access: yesJournal of Algebra, 2009
We investigate solutions for a particular class of linear equations in dendriform algebras. Motivations as well as several applications are provided. The latter follow naturally from the intimate link between dendriform algebras and Rota-Baxter operators, e.g. the Riemann integral or Jackson's q-integral.
