Abstract: I will discuss some recent work on strong-coupling expansion of leading non-planar corrections in several examples of N=2 superconformal models that are planar-equivalent to N=4 super Yang-Mills theory and dual to type II superstring in orbifolds/orientifolds of AdS5 x S5.
Starting with localization matrix model one finds that the large 't Hooft coupling asymptotics of the coefficient of non-planar correction to Wilson loop expectation value is in agreement with a universal prediction on dual string theory side.
