------------------------------------------------------------------- Mon Mar 4 08:42:01 UTC 2024 - Jan Engelhardt <jengelh@inai.de> - 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 ------------------------------------------------------------------- Wed Dec 21 00:10:28 UTC 2022 - Jan Engelhardt <jengelh@inai.de> - Update to release 3.5 * Janitorial changes only ------------------------------------------------------------------- Sun Dec 24 12:55:51 UTC 2017 - jengelh@inai.de - Update to new upstream release 3.3 * Line 542 in "expamples/examples.g" corrected * testfile in PackageInfo.g changed to "tst/testall.g" ------------------------------------------------------------------- Sat Apr 29 21:34:22 UTC 2017 - jengelh@inai.de - Update to new upstream release 3.1 * New function HeLP_AutomorphismOrbits, HeLP_IsZCKnown, HeLP_WithGivenOrderAllTables, HeLP_WithGivenOrderAndPAAllTables, HeLP_WriteTrivialSolution. ------------------------------------------------------------------- Sun Jun 19 23:56:28 UTC 2016 - jengelh@inai.de - 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. ------------------------------------------------------------------- Fri Mar 11 22:51:34 UTC 2016 - jengelh@inai.de - Initial package (version 2.2) for build.opensuse.org
