On the resonance problem with nonlinearity which has arbitrary linear growth

This paper deals with the nonlinear two-point boundary value problem at resonance. Even nonlinearities g with an arbitrary linear growth in +∞ (resp. −∞) may be considered but only on the cost of the corresponding bound on their linear growth at −∞ (resp. +∞). It generalizes the previous results in this direction obtained by M. Schechter, J. Shapiro, and M. Snow (Trans. Amer. Math. Soc. 241 (1978), 69–78), L. Cesari and R. Kannan (Proc. Amer. Math. Soc. 88 (1983), 605–613), and S. Ahmad (Proc. Amer. Math. Soc. 93 (1984), 381–384).
