Ito's Lemma is named for its discoverer, the brilliant Japanese mathematician Kiyoshi Ito. The human race lost this extraordinary individual on November 10, 2008. He died at age 93. His work created a field of mathematics that is a calculus of stochastic variables. APPENDIX WA: DERIVATION OF ITO'S LEMMA In this appendix we show how Ito's lemma can be regarded as a natural extension of other, simpler results.

Itōs lemma (Itōs formel) är ett berömt resultat inom den gren av matematiken som kallas stokastisk analys (stokastisk kalkyl). Det är uppkallat efter Kiyoshi Itō.

1. For the “contributes” to the process. 2. Next, we want to get a better intuition for Ito's Lemma by taking. which is a special case of an Ito Process. But we have also seen that by applying Ito's Lemma, the natural log of the stock price follows the simpler.

Then d(X t ·Y t) = X t dY t +Y t dX t +dX t dY t. • Note: We calculate the last term using the multiplication table with “dt’s” and “dB t’s” Das Lemma von Itō (auch Itō-Formel), benannt nach dem japanischen Mathematiker Itō Kiyoshi, ist eine zentrale Aussage in der stochastischen Analysis. In seiner einfachsten Form ist es eine Integraldarstellung für stochastische Prozesse, die Funktionen eines Wiener-Prozesses sind. Es entspricht damit der Kettenregel bzw.
