The dynamics of the HIV infection: a time-delay differential equation approach
differential equation model time-delay three-stage dynamics
2010/4/6
In this work we introduce a differential equation model with time-delay that describes the three-stage dynamics and the two time scales observed in HIV infection. Assuming that the virus has high muta...
A new method of solving singular multi-pantograph delay differential equation in reproducing kernel space
Exact solution singular two-point value boundary problem multipantograph
2010/9/13
In this paper, we present a new method for solving singular twopoint boundary value problem for multi-pantograph delay differential equation having singular coefficients. Its exact solution is represe...
