Existence and uniqueness of solutions for vector problems containing small parameters
The authors gives criteria for the existence of at least a solution of the two-point boundary value problem for the differential system \(\epsilon y_ i''+a_ i(x,y_ 1,y_ 2)y_ i'+b_ i(x,y_ 1,y_ 2)=0,\) \(i=1,2\), \(0\leq x\leq 1\), containing the small parameter \(\epsilon >0\).
