Version 3.1.0-1 of "Singular" has been uploaded.
About: SINGULAR is a Computer Algebra System for polynomial computations with special emphasis on the needs of commutative algebra, algebraic geometry, and singularity theory. NEWS and CHANGES in SINGULAR 3-1-0 (You will also find this and more detailed information at http://www.singular.uni-kl.de/Manual/3-1-0/sing_1575.htm) * new coefficients: Z, Z/m, Z/(2^n) (see Rings and orderings) * new handling of the default argument in libraries (see Parameter list) * ESingular updated for emacs 22 * licences for all parts of SINGULAR clarified (see Preface) New SINGULAR functions * new command: kernel (see kernel) * new command: sqrfree (see sqrfree) * command changed: the first argument to monitor should be an ASCII link. (see monitor) * command extended: eliminate: variables to eliminate may also be given as intvec. (see eliminate) Internal Changes * handling of large input for std improved * interred implemented in a different way * kbase honors the attribute "isHomog" * jacob accepts modules and matrices * gcd over algebraic extensions of the rationals implemented in a different way * new build target: libsingular.a (for gfan etc.) * code variants now depend on CPU type, not OS * better test for built-in limits (see Limitations) * operator new(size_t,const std::nothrow_t&) now also overloaded New SINGULAR libraries * surfex: new version 0.90 * new library: redcgs.lib * new library: tropical.lib * new library: polymake.lib * new library: sing4ti2.lib * new library: decodegb.lib * new library: dmodapp.lib * new library: bfun.lib global * new library: freegb.lib * new library: jacobson.lib * contributed library: cimonom.lib * contributed library: phindex.lib Changed SINGULAR libraries * normal.lib ( normal_lib): changed structure of the result, new algorithms have been implemented which improve performance * elim.lib ( elim_lib): elim, nselect, select, select1: changed syntax * homolog.lib: kernel renamed to hom_kernel. * matrix.lib ( matrix_lib): new commands for computing symmetric/exterior powers/bases * surf.lib: new command surfer: interface to program surfer * teachstd.lib ( teachstd_lib): spoly works now in non-commutative algebras and standard can thus be used there. However, since product criterion is a priori not applicable in the non-commutative case, one may want to disable it first * many changes of names in libraries (to have a more consistent naming scheme) Frank Seelisch seeli...@mathematik.uni-kl.de -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
