In the current state of the art as regards physcal representaton of the formulas n the electronc documents, n the absence of DTD (Descrpton of the Type of Document to formalsm SGML), those are comparable to drawngs. They thus do not undergo reformatng accordng to the meda of consultaton (paper, cathode screens). The e-book comprses as many external fles of formulas (drawngs). The contents of these fles come to be dsplayed wth the consultaton of the book to the ste whch t must have n the text. The book comprses a table connectng the name of the fle (the formula) and the poston n the book. 1. Standards and recommendatons Aster They ndcate the manner typographcally of representng the types of the mathematcal objects most frequently handled by the mechancs of the sold. The prncple s the use of typographcal enrchments Italc and Fat to typfy these objects. The wrter Aster wll use of these recommendatons whch consttute an acceptable mnmal representaton by the communty of the mechancs of the sold developng n Aster.
