Some implications of a new definition of the exponential function on time scales

open access: yes, 2010
We present a new approach to exponential functions on time scales and to timescale analogues of ordinary differential equations. We describe in detail the Cayley-exponential function and associated trigonometric and hyperbolic functions. We show that the

New definitions of exponential, hyperbolic and trigonometric functions on time scales

open access: yes, 2010
We propose two new definitions of the exponential function on time scales. The first definition is based on the Cayley transformation while the second one is a natural extension of exact discretizations.

On the exact discretization of the classical harmonic oscillator equation

open access: yes, 2009
We discuss the exact discretization of the classical harmonic oscillator equation (including the inhomogeneous case and multidimensional generalizations) with a special stress on the energy integral.
