In this report, the class of semilinear sets is shown to be the least class of sets which contains all of the stratified semilinear sets and is closed under finite intersection.

We prove in this paper that every semilinear set is a finite union of disjoint linear sets, using elementary combinatorial-topological lemmas. This paper gives a positive answer to an open problem proposed by Seymour Ginsburg in his book ([2], p. 195). Let N denote the nonnegative integers and R d
## MSC (2000) 03C64 We calculate the universal Euler characteristic and universal dimension function on semilinear and semibounded sets and obtain some criteria for definable equivalence of semilinear and semibounded sets in terms of these invariants.
We use bifurcation theory to study positive, negative, and sign-changing solutions for several classes of boundary value problems, depending on a real parameter . We show the existence of infinitely many points of pitchfork bifurcation, and study global properties of the solution curves.
