Through careful mapping of the physiology of the T-zone and GC B-blast dynamics to a mathematical representation of the cell processes including proliferation, migration, differentiation, and cell death, a mathematical model is constructed to capture the dominant nominal primary, late follicular, an
Let a decision policy ~r correspond to a twodimensional stochastic process {tzlr(t), Lt'}, with 0 < tx~(t) \_< 1 where 1-tx,( 0 denotes the fraction of the incoming claims at time t that is reinsured and L," denotes the total payout of dividend up to time t. When applying policy ~-the reserve of the
Yushkevich can also be applied to certain models where control of the flow is possible. The method consists in a transformation to a model without control of the flow by a kind of time change.
The problem of determining optimal retention levels for a non-life portfolio consisting of a number of independent sub-portfolios was first discussed by de Finetti (1946). He considered retention levels to be optimal if they minimized the variance of the insurer's profit from the portfolio subject t
