Positive Solutions of Singular and Nonsingular Fredholm Integral Equations

The existence of positive solutions of the Fredholm nonlinear equation y ( t ) = h ( t ) + i T k ( t ,s )[ f ( y ( s ) )+ g(y(s))]d s is discussed. It is assumed that f is a continuous, nondecreasing function and g is continuous, nonincreasing, and possibly Singular
