On the Topology of SC- and P-Manifolds,s of .-manifolds which are not isometric to a CROSS, the so-called Zoll manifolds. Observe, however, that the underlying differentiable manifold in these examples is the standard sphere. In this chapter we will prove that, at least topologically, the .-manifolds are not very different from CROSSes.

Sturm-Liouville Equations all of whose Solutions are Periodic, after F. Neuman, In the literature on differential equations there is a wide variety of books and monographs devoted to the Sturm-Liouville equation. We have selected as a reference since it inspired part of the work by F. Neuman..In B.II we analyze how a vector-valued Sturm-Liouville equation is associated wi
