Die Phänomene in Medizin und Computational existence Sciences lassen sich in wachsendem Maße mit mathematischen Modellen beschreiben. In diesem Buch werden Mechanismen der Modellbildung beginnend von einfachen Ansätzen (z. B. exponentielles Wachstum) bis zu Elementen moderner Theorien, wie z. B. unterschiedliche Zeitskalen in der Michaelis-Menten-Theorie in der Enzymkinetik, vorgestellt.

Tino' expressing the "dynamics" eventually nonlinear. as a function of In the well-known case of a Gauss-measure on E'c one has no:2 and then [7] Tn m ® (n-2k) i~ k : k __E T1 (~T2 0 [~ , m= Another application which is under investigation is to the Euclidean approach to quantum field theory. This is basically a special case of the above case but in addition one has to incorporate various concrete properties for the moments and has some ideas about the form of the differential equation. Kotelenez (eds.

Moreover, i f the control m is optimal then the integrand is i d e n t i c - a l l y zero and i f one assumes f u r t h e r that v is such that the l a s t term is a martin- gale, one obtains a supermartingale i n e q u a l i t y version of the p r i n c i p l e of o p t i m a l i t y . PI. Optimality p r i n c i p l e For any admissible and only i f Mt m, Mt is a supermartingale and ~ is optimal i f is a martingale. This martingale o p t i m a l i t y p r i n c i p l e means that the f a i l u r e to switch at time the optimal control e n t a i l s a u t i l i t y loss of i f one persists in using a non-optimal control over the time i n t e r v a l [ s , t ] .

Malliaris (1981) gives a f u l l account of applications of It6 calculus to economic prob- lems. Now, we are in a position to formulate our optimization problem as the following completely observable stochastic control problem: Find admissible time path {Sk2(t)}, {L2(t )} {~(t)} or, equivalently, find admissible time paths such that the mathematical expectation of the functional i t U(k2(t)' a ( t ) ) d t + g(k2(t*)) (10) 0 reaches i t s supremum subject to eq. (9) and the constraints related to eq.
