Abstract

Certain elliptic equations arising in catalysis theory can be transformed into ordinary differential equations on the interval (0,). The solutions to these problems usually depend on parameters ρn, say u(t,ρ). For certain types of nonlinearities, we show that the boundary value u˙(,ρ) is continuous on compact sets of the variable ρ. As a consequence, bifurcation results for the elliptic equation are obtained.
