I was never able to understand differential equations on wiki (probably because I'm not good with differentials ) but is it a kind of functional equation?
Like you have a field with a third operation (i think is called composition algerba)\( (F,+,\cdot,\circ) \) a function \( ':F \rightarrow F \) and you have to solve( in your case) for the \( \chi \)
\( \chi' \cdot t=g\circ \chi \)
in your case \( t(x)=x^A \)
Im getting it in the right way? But \( '=D \) is the differentiation operator (or how is called...)?
