The instability region turned out to be closely associated with the values of the so-called coupling constants: numerical coefficients by which the corrections to Einstein's equation are multiplied.

The existence and stability properties of a class of partial functional differential equations are investigated. The problem is formulated as an abstract ordinary functional differential equation of ...

The stability constants of finite difference schemes approximating linear mth order integro-differential equations are shown to converge to their continuous counterparts. Journal Information SIAM ...
