Boundaries, inclusions and disorder in active matter

Summary

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

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

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

V.    Phase separation: Destruction of bulk phase separation by disorder

VI.   Boundary disorder: Boundary disorder disrupts bulk order
