Problemstellung und Stand der Forschung,s, we consider the initial value problem . Physically, this problem is a model of heat flow in an infinitely long bar where the initial temperature ϕ(.) is prescribed. In a chemical or biological context, the equation governs density variations under a diffusion process. Notice that there are no bou

(we assume that the independent variables are . and .) in an initial boundary value problem can be written as a product of a function of . and a function of ., that is, .(., .) = .(.).(.). Thus, the variables separate. If the method is to be succe

In this chapter we extend these ideas to more complicated phenomena involving age structure of a population, the propagation of epidemic waves, and the relationship between spatial pattern formation and chemical instability. These advanced models will show why PDEs have vast application in t

AIDS XVII, Mexico City: Reason for Hope or Panic?,ked out any discussion or open forum on the issue in Mexico, and were quick to claim, “the train has already left the station.” How soon this first-time public health condemnation of a normal body part, an apparent well-financed fait accompli, stumbles remains the interesting question.
