 bsp\;<br>I will describe the abstract commensurability classification with
 in a  class of hyperbolic right-angled Coxeter groups. I will explain the 
  relationship between these groups and a related class of geometric  amalg
 ams of surface groups\, and I will highlight the differences between  the 
 quasi-isometry classification and abstract commensurability  classificatio
 n in this setting. This is joint work with Pallavi Dani and  Anne Thomas.&
