A graph G is said to be n-factor-critical if G − S has a 1-factor for any S ⊂V (G) with |S| = n. In this paper, we prove that if G is a 2-connected n-factor-critical graph of order p with 3(G)¿ 2 (p−n−1), then G is hamiltonian with some exceptions. To extend this theorem, we de6ne a (k; n)-factor-critical graph to be a graph G such that G − S has a k-factor for any S ⊂V (G) with |S| = n. We con...
Avila and Molina [1] introduced the notion of generalized weak structures which naturally generalize minimal structures, generalized topologies and weak structures and the structures α(g),π(g),σ(g) and β(g). This work is a further investigation of generalized weak structures due to Avila and Molina. Further we introduce the structures ro(g) and rc(g) and study the properties of the structures r...
the families of tgf-β proteins are the most important growth factors in the ovary for growth and differentiation of early ovarian follicles. three related oocyte-derived members of the transforming growth factor-β superfamily namely growth differentiation factor 9 (gdf9), bmp15 and bmpr-ib have been shown to be essential for follicular growth and ovulation. different mutations in the gdf9 gene ...
