Rational Hadamard products via Quantum Diagonal Operators
Gérard Henry Edmond Duchamp, Silvia Goodenough, Karol A. Penson
We use the remark that, through Bargmann-Fock representation, diagonal operators of the Heisenberg-Weyl algebra are scalars for the Hadamard product to give some properties (like t…
Moderate Growth Time Series for Dynamic Combinatorics Modelisation
Luaï Jaff, Gérard H. E. Duchamp, Hatem Hadj Kacem +1
Here, we present a family of time series with a simple growth constraint. This family can be the basis of a model to apply to emerging computation in business and micro-economy whe…
Free quasi-symmetric functions, product actions and quantum field theory of partitions
Gerard Henry Edmond Duchamp, Jean-Gabriel Luque, Karol A. Penson +1
We examine two associative products over the ring of symmetric functions related to the intransitive and Cartesian products of permutation groups. As an application, we give an enu…
