A graph G with a perfect matching is called saturated if G + e has more perfect matchings than G for any edge e that is not in G. Lovász gave a characterization of the saturated graphs called the cathedral theorem, with some applications to the enumeration problem of perfect matchings, and later Szigeti gave another proof. In this paper, we give a new proof with our preceding works which reveal...

This paper is on matching theory. A graph with perfect matching is called saturated if any addition of one complement edge creates a new perfect matching. Lovász gave a characterization of the saturated graphs called the cathedral theorem, and later Szigeti gave another proof. In this paper, we gave a new proof with our preceding works, which revealed the canonical structure of general graph wi...

Our country’s textile industry is in the producing and processing field in the global value chain, so textiles’ added value is low and profit margins is narrow. Developed countries take up fields of high-grade fabrics production and advanced textile machinery manufacture. Because textile fabrics, textile machinery and equipment of China's textile industry fall behind developed countries, produc...
