Fourth-order compact exponential splittings for unbounded operators
Juan Carlos Del Valle, Arieh Iserles, Karolina Kropielnicka
We present a derivation and error bound for the family of fourth order splittings, originally introduced by Chin and Chen, where one of the operators is unbounded and the second on…

Splitting methods for unbounded operators
Arieh Iserles, Karolina Kropielnicka
This paper considers computational methods that split a vector field into three components in the case when both the vector field and the split components might be unbounded. We fi…

An elementary approach to splittings of unbounded operators
Arieh Iserles, Karolina Kropielnicka
Using elementary means, we derive the three most popular splittings of and their error bounds in the case when and are (possibly unbounded) operators in a Hilbe…
