Population Aging and its effect on a Japanese Economy

The basic virus dynamics model with humoral immune response has four state variables: x, the population of uninfected target cells; y, the population of productive infected cells;

In 1992 Greither [10] refined the method of Rubin and used the Euler system of cyclotomic units to give an elementary (but technical) proof of the second version of the Main

An easy-to-use procedure is presented for improving the ε-constraint method for computing the efficient frontier of the portfolio selection problem endowed with additional cardinality

The inclusion of the cell shedding mechanism leads to modification of the boundary conditions employed in the model of Ward and King (199910) and it will be

Let X be a smooth projective variety defined over an algebraically closed field k of positive characteristic.. By our assumption the image of f contains

In this note, we consider a second order multivalued iterative equation, and the result on decreasing solutions is given.. Equation (1) has been studied extensively on the

We present evidence on the global existence of solutions of De Gregorio’s equation, based on numerical computation and a mathematical criterion analogous to the
