With a bit of help of books.google.com I can see "adjugate" is used in this book (adjoint matrix is not used, though); however it doesn't seem to contain any reference to where this word came from. Do you know? On the other hand, searching for "The adjoint of a square matrix" bourbaki in books.google.com, yields the following passage: """ The adjoint of a square matrix X of order n over A is the matrix X = (det (A'")) of minors of A" of order n — 1. """ (bourbaki, elements, book 2, chapter III, section 11, exercise 9 -- the term also shows at the index of terminology) Best, Gonzalo -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
