Currently, comparison of free_module_generic (and free_quadratic_modules) ignores the inner product matrix
sage: FreeModule(ZZ,1)==FreeModule(ZZ,1,inner_product_matrix=matrix.identity(1)*2) True sage: FreeQuadraticModule(ZZ,1,matrix.identity(1))==FreeQuadraticModule(ZZ,1,matrix.identity(1)*2) True Especially for FreeQuadraticModules, the inner_product_matrix is essential and two FreeQuadraticModules are certainly different (mathematically) if their inner product is different. Is that intended behavior? If not, I would like to open a ticket. Do I need a deprecation warning or something for that ? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
