About me

My name is Pengcheng Li (李鹏程). I am a young algebraic topologist in Department of Mathematics, School of Sciences of Great Bay University, as an assistant professor. In June 2020, I received my Ph.D. from the Academy of Mathematics and Systems Science, University of Chinese Academy of Sciences (AMSS, CAS) under the supervision of Jianzhong PAN.

My main research interests lie in classical homotopy theory; I am particularly interested in the homotopy theory of $(n-1)$-connected $(n+2)$-dimensional finite CW-complexes (called $\mathbf{A}_n^2$-complexes) and its applications, such as modular cohomotopy groups, homotopy types of suspended or looped manifolds.
