Conifold transitions for complete intersection Calabi-Yau threefolds in products of projective spaces (Q2853998)

This work is a continuation of the author's paper [Acta Math. Sin., Engl. Ser. 28, No. 7, 1347--1368 (2012; Zbl 1256.14040)]. Instead of working on the hypersurface of toric Fano fourfolds, he worked on the three dimensional complete intersections of products of a series projective spaces. He obtained similar results. See the review of the reviewer on above mentioned article. These are generalizations of [\textit{R. Friedman}, Proc. Symp. Pure Math. 53, 103--134 (1991; Zbl 0753.14035)] and [\textit{P. Lu} and \textit{G. Tian}, in: Manifolds and geometry. Proceedings of a conference, held in Pisa, Italy, September 1993. Cambridge: Cambridge University Press. 284--293 (1996; Zbl 0854.32016)].
