Resumen de Boyd index and nonlinear Volterra equations

W. Okrasinski, Jesús María Fernández Castillo

• In mathematical models of some physical phenomena a new class of nonlinear Volterra equations appears ([5],[6]). The equations belonging to this class have u = 0 as a solution (trivial solution), but with respect to their physical meaning, nonnegative nontrivial solutions are of prime importance.
