|
|
|
|
- Update to release 4.0
|
|
* Two new global functions: HeLP_SP and HeLP_KP to study the
|
|
Spectrum Problem and the Kimmerle Problem and their companion
|
|
functions HeLP_AllOrdersSP and HeLP_AllOrdersKP
|
|
* More theoretical results are taken into account when the
|
|
system to solve is generated, namely more partial
|
|
augmentations are assumed to be 0 a priori. This includes
|
|
three results: Berman-Higman (in the general form that the
|
|
coefficient at a central element is 0, if the unit is not
|
|
that element), Hertweck's Proposition 2 from [Hertweck08] (if
|
|
a unit u has smaller order modulo a normal p-subgroup,
|
|
elements with non-zero partial augmentations must have same
|
|
p-power order as u) and Hertweck's p-adic criterion (units
|
|
which map tp 1 modulo a normal p-subgroup are p-adically
|
|
conjugate to elements in G and hence the p-part of any
|
|
element with non-zero partial augmentation is unique up to
|
|
conjugacy in G)
|
|
* Three new minor global functions: HeLP_UnitSatisfiesKP to
|
|
check manually for KP and given partial augmentaion;
|
|
HeLP_IsOneModuloN to see if a unit is mapped to the identity
|
|
modulo a normal subgroup N; HeLP_ForgetUnderlyingGroup to
|
|
obtain same table without group structure. This way the new
|
|
theretical restictions do not apply and one can obtain the
|
|
results as in older versions

|
|
|
|
- Update to new upstream release 3.0
|
|
* Normaliz is included as a possible solver.
|
|
* Functions included to switch between the solvers. For normaliz,
|
|
a function is included to influence whether normaliz computes
|
|
vertices of polyhedra.
