Existence and Nonexistence of Positive Radial Solutions for Quasilinear Systems

The paper deals with the existence and nonexistence of positive radial solutions for the weakly coupled quasilinear system div (

Nonexistence of Solutions In

Consider the KPP-type equation of the form ∆u+f (u) = 0, where f : [0, 1] → R + is a concave function. We prove for arbitrary dimensions that there is no solution bounded in (0, 1). The significance of this result from the point of view of probability theory is also discussed.

Torsion of cylindrically poroelasic circular shaft with radial inhomogeneity .some exact solutions for extruder

Torsion of elastic and poroelastic circular shaft of radially inhomogeneous, cylindrically orthotropic materials is studied with emphasis on the end effects example for extruder. To examine the conjecture of Saint-Venant’s torsion, we consider torsion of circular shaft with one end fixed and the other end free on which tractions that results in a pure torque are prescribed arbitrarily over the fr...
