 The sphere module $n{+}1$-category is a natural generalization of the 
 algebra-bimodule-intertwiner 2-category to higher dimensions.
 
-Another possible name for this $n{+}1$-category is $n{+}1$-category of defects.
+Another possible name for this $n{+}1$-category is the $n{+}1$-category of defects.
 The $n$-categories are thought of as representing field theories, and the 
 $0$-sphere modules are codimension 1 defects between adjacent theories.
 In general, $m$-sphere modules are codimension $m{+}1$ defects;
