A new parameterisation of Pythagorean triples in terms of odd and even series
Anthony Overmars, Lorenzo Ntogramatzidis
In this paper we introduce a formula that parameterises the Pythagorean triples as elements of two series. With respect to the standard Euclidean formula, this parameterisation doe…

The extended symplectic pencil and the finite-horizon LQ problem with two-sided boundary conditions
Augusto Ferrante, Lorenzo Ntogramatzidis
This note introduces a new analytic approach to the solution of a very general class of finite-horizon optimal control problems formulated for discrete-time systems. This approach…
