Chapter 6, Mishna 2
We’ve learned that one who did not join a courtyard eruv before Shabbos began may renounce his rights in the courtyard so that he won’t restrict the others from carrying there. How exactly does this work? Can one renounce to multiple people who have not established an eruv? Can multiple people who established an eruv renounce their rights to one person who did not? What if several people join in an eruv and one of them dies on Shabbos? What if the one who didn’t join the eruv dies on Shabbos before renouncing his rights – may his heir renounce them?
