Abstract (in Japanese) (See Japanese page) 
(in English) The source coding problem with encoded side information is considered. A lower bound on the strong converse exponent has been derived by Oohama, but its tightness has not been clarified. In the previous paper, we derived a tight strong converse exponent. The achievability part was derived by a careful analysis of the type argument. The converse part was proved by a judicious use of the change-of-measure argument, which was introduced by Gu-Effros and further developed by Tyagi-Watanabe. In this paper, we compare it with another network, and show that the two exponents coincide.
