On the Unconditional Stability of Implicit-Explicit BDF Methods
Prof. Georgios Akrivis
Department of Computer Science and Engineering, University of Ioannina, Greece

We study the unconditional stability of implicit-explicit backward difference formula (BDF) methods applied to Dahlquist's first test equation. This can be viewed as an attempt to extend the well-known A()-stability concept to implicit-explicit multistep methods.
