We describe certain extremalities for Gallager's E<sub>0</sub> function evaluated under the uniform input distribution over the class of binary input discrete memoryless channels; The results characterize the extremality of the E<sub>0</sub>(ρ) curves of the binary erasure channel and the binary symmetric channel among all the E<sub>0</sub>(ρ) curves that can be generated by the class of binary discrete memoryless channels whose E<sub>0</sub>(ρ) curves pass through a given point (ρ<sub>0</sub… CONTINUE READING
