Abstract

Rudyak's conjecture states that cat(M)(M) \geq cat(N)(N) given a degree one map f:MNf:M \to N between closed manifolds. We generalize this conjecture to sectional category, and follow the methodology of [5] to get the following result: Given a normal map of degree one f:MNf:M \to N between smooth closed manifolds, fibrations pM:EMMp^M:E^M \to M and pN:ENNp^N:E^N \to N, and lift f\overline{f} of ff with respect to pMp^M and pNp^N, i.e., fpM=fpNfp^M = \overline{f} p^N; then if ff has no surgery obstructions and NN satisfies the inequality 5dimN2r5 \leq \dim N \leq 2r secat(pN)3(p^N) - 3 (where the fiber of pNp^N is (r2)(r-2)-connected for some r1r \geq 1), then secat(pM)(p^M) \geqsecat(pN)(p^N). Finally, we apply this result to the case of higher topological complexity when NN is simply connected.
