[Banach] Abstract of a paper by Michael Dymond

This is an announcement for the paper "Avoiding sigma-porous sets in Hilbert spaces" by Michael Dymond. Abstract: We give a constructive proof that any $\sigma$-porous subset of a Hilbert space has Lebesgue measure zero on typical $C^{1}$ curves. Further, we discover that this result does not extend to all forms of porosity; we find that even power-$p$ porous sets may meet many $C^{1}$ curves in positive measure.
