Boundaries, inclusions and disorder in active matter

Summary

I.   Pressure in equilibrium and active matter:  Pressure dependence on boundary properties 

 II.  Boundary asymmetry and curvature:  Ratchet forces and line tension

III.   Inclusions and disorder:  The long reach of inclusions in disturbing active fluids

IV.    Phase separation and disorder: Destruction of bulk phase separation by disorder in bulk or boundary
