We shall prove a type of Mardešić factorization theorem for extension theory over an arbitrary stratum of CW-complexes in the class of arbitrary compact Hausdorff spaces. Our result provides that the ...

In this note we shall generalize the Paley-Wiener theorem to self-adjoint operators similar to (−id/dx). By using a simple factorization result, it is shown that the Paley-Wiener theorem holds if Γ′(λ ...
