This sugya addresses the concept of Nichsei Tzibbur - i.e. possessions that belong to the entire community.  What are the Halachic distinctions between a community possession (i.e. Shul, Sefer Torah, Mikveh, Korban Tzibbur, etc.) and a typical partnership?  Does each community member own a share of the community possession, as is the case with a regular partnership?  Is one then permitted to forfeit or sell his share of the community possession, as one would do when exiting or dissolving a partnership?  This sugya has ramifications in the forming of partnerships, corporations, and LLCs today, pertaining to topics such as Ribbis, Chametz, etc.
