The directives iff, implies, and in must all be executed in math mode. Separately, the emph directive does nothing here, since it's a text-mode command whereas its argument consists entirely of math-mode material.



Hence, you need to replace



A subset $C$ is emphclosed iff emph $iin C, ito j$ implies $j$ in $C$ 


with



A subset $C$ is emphclosed $iff iin C, ito j implies j in C$.


Better still, write



A subset $C$ is emphclosed if and only if $iin C, ito j$ implies $jin C$.


Of course, you may choose to write "iff" instead of "if and only if".



A full MWE:
