On a multiplicative perturbation of Laguerre polynomials

Julien Grivaux

In this article, we study the family of polynomials \[ P_n(s, z)=\sum_{k=0}^n s^{(k)} z^{n-k} \] for $s > 0$ . We prove that its roots are simple, and provide a precise localisation o…

Duality, polarity and convolution in umbral calculus

Julien Grivaux

In this paper, we revisit foundations of umbral calculus using a straightforward approach based on an explicit matrix realization of binomial convolution. We construct an umbral du…

Tian's invariant of the Grassmann manifold

Julien Grivaux

We prove that Tian's invariant on the complex Grassmann manifold $G_{p, q} (C)$ is equal to $1/ (p + q)$ .
