An upper and lower solution approach for a generalized Thomas–Fermi theory of neutral atoms
An upper and lower solution theory for boundary value problems modeled from the Thomas-Fermi equation, was presented. The approach was subjected to a boundary condition corresponding to the neutral atom with Bohr radius. ...
Random fixed point theory in spaces with two metrics
We present new random fixed point theorems in spaces with two metrics. Our results extend recent results of Tan and Yuan  and Xu .
Existence Criteria for Singular Initial Value Problems with Sign Changing Nonlinearities
A general existence theory is presented for initial value problems where our nonlinearity may be singular in its dependent variable and may also change sign.
Boundary value problems on the half line in the theory of colloids
We present existence results for some boundary value problems defined on infinite intervals. In particular our discussion includes a problem which arises in the theory of colloids.
