Fu Fengyun is an instructor at the School of Mathematic and Statistics, Guangdong University of Finance & Economics, Guangzhou, China. She received a Ph.D. degree in Science from the School of Science, Nanjing University of Science and Technology in 2012. Her research focuses on fundamental mathematics, in the field of semi-Riemannian geometrical analysis. She has given the classification of the projective equivalent semi-Riemannian metrics, and studied geometrical and topological properties of semi-Riemannian manifolds admitting projective equivalent metrics. She has published a number of papers in some important journals, such as Bulletin of the Malaysian Mathematical Sciences Society, Journal of Geometry and Physics and Nonlinear Analysis. Finally, she has participated in a National Natural Science Foundation of China.
