Open Problems in Exponentially Fitting

7 Open Problems in Exponential Fitting. - In future years it will be interesting to investigate the following about exponential fitting  

The construction of high algebraic order exponentially-fitted methods. 

The combination of the property of exponential fitting with the property of phase-fitted (see below). 

The construction of Runge-Kutta and Runge-Kutta-Nystrom exponentially-fitted methods.
