We are concerned with the fourth-order nonuniform cantilever beam problem
= f x,W(x) ,
W(a) = W (a) = 0, I(b)W (b) = (I(x)W (x)) |x=b = 0. Under various assumptions on f we
prove the existence of at least one, two, or three positive solutions for this measure chain boundary value
problem using the Green function approach.
