Aproximate Cycles of the Second Kind in Hilbert space for a Generalized Barbashin-Ezeilo Problem

In this work we show that the Volterra integral operator defined on the space of absolutely stable functions induces an asymptotically pseudocontractive operator. We, then, show that Afuwape’s [1] generalization of the Barbashin-Ezeilo problem is solvable in a Banach space (but not in Hilbert space L₂[0,∞)). However applying Osilike-Akuchuf[10] theorem and recent results (in Hilbert space) of Igbokwe and Udoutun[8] we formulate conditions for finding approximate cycles of the second kind (in the Hilbert space W₀^2,2[0,∞)) to this problem given in the form x'" + ax" + g(x') + φ(x)= 0
