Description: As shown in particular in
[32]
, Pommaret bases are well suited for
computing resolutions and allow for the easy determination of the Castelnuovo-Mumford
regularity and the projective dimension. In this work, we generalise these ideas to
Pommaret-like bases which are usually smaller. Furthermore, we show that they can
also be applied to ideals in quotient rings. For the case of Clements-Lindström rings,
we characterise some classes of ideals where one even obtains a minimal resolution. |
