Předpodmiňovače FETI-DP, BDDC a P-FETI-DP jsou odvozeny jednoduchým abstraktním způsobem. Je ukázáno, že jejich vlastnosti lze získat pouze z několika algebraických předpokladů. (cs)
The FETI-DP, BDDC and P-FETI-DP preconditioners are derived in a particulary simple abstract form. It is shown that their properties can be obtained from only a very small set of algebraic assumptions.
