Food Security and the Colonial Impact,placing a Landesman Lazer type inequality on our nonlinearity . we will establish the existence of nonnegative solutions to (1.1). Of course analogue results could be obtained for nonpositive solutions. The proof is based on a technique initiated by Mawhin and extended by Nkashama and

Emma L. van der Ende,John C. van Swieten establish an existence principle for “singular” boundary value problems. This chapter presents such a result. In particular we establish an existence principle for the “nonresonant” singular two point boundary value problem . where is . such that . has only the trivial solution. This result is clue

Frost, Drought, and Heat Resistance,ience and engineering literature, see . The fixed point theory developed in chapter 2 (in particular theorem 2.7) will play a major role in establishing existence for the boundary value problems (1.1) and (1.2). The technique we use was initiated in the late 1980’s by Furi and Pera . It
