On a special class of nonlinear integral equations
The author considers nonlinear integral equations not of the standard type \[ \varphi \bigl( t,x(t) \bigr) + \int^1_0 \psi \bigl( t,s,x(t), x(s) \bigr) ds = 0 \quad \text{for } t \in [0,1] \] with a certain monotonicity in the argument \(y = x(t)\) and a certain compactness in the argument \(x = x(s)\).
