Vito Volterra

Vito Volterra (1860-1940) used to be the most well-known representatives of Italian technology in his day. Angelo Guerragio and Giovanni Paolini research Volterra's most vital contributions to arithmetic and their functions, in addition to his awesome organizational achievements in medical coverage.

Suppose that b E~. (X g(~ , b E~). Then F(b) = O. 1) F(bac) = ~(a)o~F(b) (b ~ , Proof. (H e O~). c ~7)2, a ~(I). From property 2) above, it is clear that if X e ~, F(X) = 0. Property B) implies that the kernel of F is a left ideal in 9 . Hence the kernel of F contains ~ , Let ~ ( J ) = C + ~c ~ ( J )analogously. F(c) = c ~ (c ~ ) . as claimed. 1), we show first that If c = V e 9T~, we find using 2) that F(V) = - V = V ~. Assume that F(c) = c ~ if c a ~ ( J ) ; and assume that c ~ o~(J), V c Ogq.

If XI, X2 e ~ l , then q(Xl)¢i(x2) - Q(x2)~i(xi) = ~/[Xl,X2]). Proof. We have q(X1)q(X2)I = q ( X 1 ) ( ¢ i ( X 2 ) I ) = (q(X1)¢I(X2))I + ¢I(X2)q(XI)I = (q(X1)¢l(X2))l + ¢I(XI)¢I(~)I, Hence, [q(Xl) , q(X2)]I = {q(Zl)¢i(X2) - q(X~(Xl)}i" Also, [q(Xl) , q(X2)]I = q([XI,X2])I = ¢I([XI,X2])I. Therefore, ¢i([Xl,X2])I = {~(×l)¢i(x 2) - q(z2)¢i(Xl)}I. Since ~ is an integral domaih and I # 0 by assumption, we may cancel I to obtain the desired identity. 5. Suppose that X1,X2 ~ i " Then 46 FI(X 1 ® X 2 - X 2 ® X 1 - [X1,X2]) = 0, Proof.

Proof. 1, Let IR(~:m) = ]V(R)f(~l~;X_yIm)d~.
