%0 Journal Article %T Minimal number of edges in hypergraph guaranteeing perfect fractional matching and MMS conjecture, complete version %A Vladimir Blinovsky %J Mathematics %D 2015 %I arXiv %X In this paper we prove Ahlswede- Khachatrian conjecture~\cite{1} up to finite number of cases, which can be checked using modern computers. From this conjecture follows conjecture from~\cite{2} and Manickam-Mikl\'{o}s-Singhi conjecture. This paper is combined from papers~\cite{09},~\cite{08}. %U http://arxiv.org/abs/1510.01144v1
