Coincidence degree theory was developed by Jean Mawhin in the early 1970s as an extension of the Leray-Schauder degree. The theory applies to study of equations of the form

$ Lu =N(u) +f,  $

where $ N\colon X\to Y $ is a continuous map between Banach spaces, $ X $ and $ Y $,

$  L\colon\mbox{Dom}(L)\subset X\to Y  $

is a Fredholm operator of index $ 0 $, and $ f\in Y $. In this talk we outline the coincidence degree theory in the context of its applications to certain semilinear two--point boundary value problems under conditions of resonance.
