Ticket #4539 – Description
v14 v18 1 During SD10 in Nancy, Michael Brickenstein and Burcin Erocal worked on making Plural (the noncommutative extension of Singular) accessible from Sage. 1 During SD10 in Nancy, Michael Brickenstein and Burcin Erocal worked on making Plural (the noncommutative extension of Singular) accessible from Sage. (Burcin and Michael also worked at the Plural wrapper on SD 23.5 in Kaiserslautern.) Oleksandr Motsak and Alexander Dreyer continued this at SD 24 in Linz. 2 2 3 The patches that resulted from this work are attached. 3 The patches that resulted from this work are attached. 4 4 5 5 Newest functionality: 6 6 7 * noncommutative rings/polynomials/ideals are fully featured classes now (no deriving from commutative ones)! 7 8 * coercion from basering/Integer types (still needs tests) 8 9 * flag to check degeneracy conditions on init 9 * relations for noncommutative rings 10 * most relevant functions for rings/polynomials/ideals (mostly adopted from MPolynomialRing_libsingular/MPolynomialRing_libsingular/...) 11 e.g. std/twostd/syzygy_module/lc/lm/lt/monomial operations 10 * relations for noncommutative rings 11 * most relevant functions for rings/polynomials/ideals (mostly adopted from MPolynomialRing_libsingular/MPolynomialRing_libsingular/...) e.g. std/twostd/syzygy_module/lc/lm/lt/monomial operations 12 12 * RingWrap and TermOrder were extended 13 13 * quick and dirty conversion of RingWrap to Sage rings (needs some care as the resulting rings may not be unique and therefore may confuse coercion) … … 15 15 * shortcut to create graded commutative algebras: SCA 16 16 17 Possible topics that need work are: 17 18 18 Possible topics that need work are:19 19 * put the files in sage/algebra/ ??? 20 20 * make sure element does not export functions it doesn't support (e.g. gcd) 21 * predefined structures from the library 22 23 21 * predefined structures from the library
