Why do you say that the ring accent \[ao] is too big? What font are you using? I think that the ring accent of Times Roman is actually quite small; I would rather use the degree symbol: .\" eqn .EQ delim $$ sdefine comp1 % type operator roman "\v'.34m'\(ao\v'-.34m'" % sdefine comp2 % type operator font S "\v'.26m'\(de\v'-.26m'" % sdefine comp3 % type operator "\s'-2'\v'-.09m'\(ci\v'.09m'\s'+2'" % .EN .sp 3c $(f comp1 g)(x) = f(g(x))$ alignment test: $ + comp1 + comp1 + $ .br $(f comp2 g)(x) = f(g(x))$ alignment test: $ + comp2 + comp2 + $ .br $(f comp3 g)(x) = f(g(x))$ alignment test: $ + comp3 + comp3 + $ .br
