Sheaves On Graphs, Their Homological Invariants, And A Proof Of The Hanna Neumann Conjecture (memoirs Of The American Mathematical Society, January 2015)
معرفی کتاب «برگهای روی گرافها، ویژگیهای همولوژیکی آنها و اثبات حدس هانا نیومن» (با عنوان لاتین Sheaves On Graphs, Their Homological Invariants, And A Proof Of The Hanna Neumann Conjecture (memoirs Of The American Mathematical Society, January 2015)) نوشتهٔ Joel Friedman; with an Appendix by Warren Dicks، منتشرشده توسط نشر American Mathematical Society در سال 1100. این کتاب در فرمت pdf، زبان انگلیسی ارائه شده است.
In this paper the author establishes some foundations regarding sheaves of vector spaces on graphs and their invariants, such as homology groups and their limits. He then uses these ideas to prove the Hanna Neumann Conjecture of the 1950s; in fact, he proves a strengthened form of the conjecture.
