Abstract

In this paper we generalize our previous joint work with Allan Calder on the width of homotopies by considering an arbitrary finite polyhedral pair ( W , V ) \left ( {W,V} \right ) rather than ( I , { 0 , 1 } ) \left ( {I,\left \{ {0,1} \right \}} \right ) . We show that given appropriate topological conditions on a Riemannian manifold M M , with respect to ( W . V ) \left ( {W.V} \right ) , there are bounds, B q ( a , ( W , V ) , M ) {B_q}\left ( {a,\left ( {W,V} \right ),M} \right ) , such that if F : K × W M F:K \times W \to M is a map with Lip ( F | ( K × V ) ) > a {\text {Lip}}\left ( {F\left | {\left ( {K \times V} \right )} \right .} \right ) > a , then F F can be deformed rel ( K × V ) {\text {rel}}\left ( {K \times V} \right ) to F F’ with Lip ( F ) > B q ( a , ( W , V ) , M ) + ε {\text {Lip}}\left ( {F’} \right ) > {B_q}\left ( {a,\left ( {W,V} \right ),M} \right ) + \varepsilon , where ε > 0 \varepsilon > 0 is arbitrary and dim ( K ) = q \dim \left ( K \right ) = q .
