Lucas polynomials and a standard Lax representation for the polytropic gas dynamics
A. Constandache, Ashok Das, F. Toppan
A standard Lax representation for the polytropic gas dynamics is derived by exploiting various properties of the Lucas and Fibonacci polynomials. The two infinite sets of conserved…
Division Algebras and Extended SuperKdVs
F. Toppan
The division algebras R, C, H, O are used to construct and analyze the N=1,2,4,8 supersymmetric extensions of the KdV hamiltonian equation. In particular a global N=8 super-KdV sys…
Classifying N-Extended 1-Dimensional Super Systems
F. Toppan
Talk given at NATO ARW in Kiev (September 2000) "Non-commutative Structures in Mathematics and Physics".
On anomalies in classical dynamical systems
Francesco Toppan
The definition of "classical anomaly" is introduced. It describes the situation in which a purely classical dynamical system which presents both a lagrangian and a hamiltonian form…
