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 . We prove that its roots are simple, and provide a precise localisation o…
On the isotropy stratification of a real representation of a compact Lie group
Perla Azzi, Rodrigue Desmorat, Julien Grivaux +1
The aim of the present paper is to provide a comprehensive introduction to some algebraic and geometric aspects of real representations of compact Lie groups, as well as some resul…
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…
Koszul complexes and derived intersections
Tristan Bozec, Julien Grivaux
The aim of this article is to provide a complementary understanding to some results of the second author using the machinery of Koszul complexes, and to explain how this approach c…
