We introduce the k-generalized gamma function Γk, beta function Bk, and Pochhammer k-symbol (x)n,k. We prove several identities generalizing those satisfied by the classical gamma function, beta… (More)

We introduce the q,k-generalized Pochhammer symbol. We construct $\Gamma_{q,k}$ and $B_{q,k}$, the q,k-generalized gamma and beta fuctions, and show that they satisfy properties that generalize those… (More)

We present a study of the Gaussian q-measure introduced by Diaz and Teruel from a probabilistic and from a combinatorial viewpoint. A main motivation for the introduction of the Gaussian q-measure is… (More)

Coupled biological-physical models of carbon-nitrogen cycling by phytoplankton, zooplankton, and bacteria assess the impacts of nitrogen fixation and upwelled nitrate during new production within the… (More)

We study quantum deformations of Poisson orbivarieties. Given a Poisson manifold $(\mathbb{R}^{m},\alpha)$ we consider the Poisson orbivariety $(\mathbb{R}^{m})^{n}/S_{n}$. The Kontsevich star… (More)

The study of Rota–Baxter algebras was initiated by Baxter in his works [2, 3]. The theory was later taken over by Rota [11], who gave an explicit construction of free Rota– Baxter algebras and… (More)
