Forward Symplectic Integrators and the Long Time Phase Error in Periodic Motions
S. R. Scuro, S. A. Chin
We show that when time-reversible symplectic algorithms are used to solve periodic motions, the energy error after one period is generally two orders higher than that of the algori…

Exact evolution of time-reversible symplectic integrators and their phase error for the harmonic oscillator
Siu A. Chin, Sante R. Scuro
The evolution of any factorized time-reversible symplectic integrators, when applied to the harmonic oscillator, can be exactly solved in a closed form. The resulting modified Hami…

Timelike Hopf Duality and Type IIA^* String Solutions
C. N. Pope, A. Sadrzadeh, S. R. Scuro
The usual T-duality that relates the type IIA and IIB theories compactified on circles of inversely-related radii does not operate if the dimensional reduction is performed on the…
