This thesis generalises a result of M. Walsh by proving that Gromov–Lawson concordance implies isotopy in the space of Riemannian metrics with positive (p, n)-intermediate scalar curvature. We work in the setting of closed, simply-connected manifolds of dimension n → 5, equipped with Morse functions that satisfy suitable admissibility and cancellation conditions. Building on the surgery stability results of Gromov-Lawson and Labbi, we construct a relative isotopy between specific metrics and use it to prove that any Gromov–Lawson (sp,n > 0)- concordant metrics are isotopic through positive (p, n)-intermediate scalar curvature metrics. The main result shows that for a closed, simply-connected manifold M of dimension at least 5, Gromov–Lawson concordance implies isotopy in Rsp,n>0(M), thereby extending the known relationship between isotopy and concordance from the scalar curvature case to the intermediate curvature setting.
