Abstract

We study several different types of BPS flows within minimal N=1\mathcal{N}=1, D=7D=7 supergravity with SU(2)\textrm{SU}(2) gauge group and non-vanishing topological mass. After reviewing some known domain wall solutions involving only the metric and the R+\mathbb{R}^{+} scalar field, we move to considering more general flows involving a "dyonic" profile for the 3-form gauge potential. In this context, we consider flows featuring a Mkw3\textrm{Mkw}_{3} as well as an AdS3\textrm{AdS}_{3} slicing, write down the corresponding flow equations, and integrate them analytically to obtain many examples of asymptotically AdS7\mathrm{AdS}_7 solutions in presence of a running 3-form. Furthermore, we move to adding the possibility of non-vanishing vector fields, find the new corresponding flows and integrate them numerically. Finally, we discuss the eleven-dimensional interpretation of the aforementioned solutions as effective descriptions of M2M5\mathrm{M2}-\mathrm{M5} bound states.
