Abstract: We define the notion of a ``framed function'' on a compact smooth manifold $ N$ and we show that the space of all framed functions on $ N$ is $ (\operatorname{dim} \,N - 1)$-connected. A framed function on $ N$ is essentially a smooth function $ N \to \mathbf{R}$ with only Morse and birth-death singularities together with certain additional structure.
