Page 271 - ... the original units may be replaced by linear functions of these units, so as to give rise, for the units finally adopted, to a multiplication table of the most simple form; and it is very remarkable, how frequently in these simplified forms we have nilpotent or idempotent symbols (i...
Page 271 - ... and consequently how simple are the forms of the multiplication tables which define the several systems respectively. I have spoken of this multiple algebra before referring to various geometrical theories of earlier date, because I consider it as the general analytical basis, and the true basis, of these theories. I do not realise to myself directly the notions of the addition or multiplication of two lines, areas, rotations, forces, or other geometrical, kinematical, or mechanical entities;...

Page 282 - ... merits were fully recognized by De Morgan and acknowledgments of indebtedness were frankly made by Hamilton. Throughout Warren's work the term quantity, like Cauchy's geometric quantity, indicates a line given in length and direction. Some of his definitions are as follows : The sum of two quantities is the diagonal of the parallelogram whose sides are the two quantities. The first of four quantities is said to have to the second the same ratio which the third has to the fourth ; when the first...

IV., with notes and addenda by his son, CS Peirce) ; we here consider symbols A, B, &c.
Page 270 - X greater than 3, of the equation = z\ has given rise to investigations of very great interest and difficulty. Outside of ordinary mathematics, we have some theories which must be referred to : algebraical, geometrical, logical. It is, as in many other cases, difficult to draw the line ; we do in ordinary mathematics use symbols not denoting quantities, which we nevertheless combine in the way of addition and multiplication, a + b, and ab, and which may be such as not to obey the commutative law...
Page 281 - C'est un nouvel adjectif joint au substantif ordinaire i, et non un nouveau substantif. Mais que veut dire ce signe ? Il n'indique ni une addition, ni une soustraction, ni une suppression, ni une opposition par rapport aux signes + et — . Une quantité accompagnée de \/— l n'est ni additive, ni soustractive, ni égale à zéro. La Es qualité marquée par \/ — i n'est opposée ni à cell« qu'indiqué -|-, ni à celle qui est désignée par — .

But I do separate from ordinary mathematics the system of multiple algebra or linear associative algebra, developed in the valuable memoir by the .late Benjamin Peirce, Linear Associative Algebra (1870, reprinted 1881 in the...
