  • Ticket #4539 – Description

    v14 v18  
    1 During SD10 in Nancy, Michael Brickenstein and Burcin Erocal worked on making Plural (the non-commutative extension of Singular) accessible from Sage. 
     1During SD10 in Nancy, Michael Brickenstein and Burcin Erocal worked on making Plural (the non-commutative 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.

    55Newest functionality: 
     6 
    67 * non-commutative rings/polynomials/ideals are fully featured classes now (no deriving from commutative ones)! 
    78 * coercion from basering/Integer types (still needs tests) 
    89 * flag to check degeneracy conditions on init 
    9  * relations for non-commutative 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 non-commutative 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 
    1212 * RingWrap and TermOrder were extended 
    1313 * 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) 
     
    1515 * shortcut to create graded commutative algebras: SCA 
    1616 
     17Possible topics that need work are: 
    1718 
    18 Possible topics that need work are: 
    1919 * put the files in sage/algebra/ ??? 
    2020 * make sure element does not export functions it doesn't support (e.g. gcd) 
    21  * predefined structures from the library
