Technical Debt Management in OSS Projects: An Empirical Study on GitHub
Zengyang Li, Yilin Peng, Peng Liang +4
Technical debt (TD) refers to delayed tasks and immature artifacts that may bring short-term benefits but incur extra costs of change during maintenance and evolution in the long t…
The growth of the number of periodic orbits for annulus homeomorphisms and non-contractible closed geodesics on Riemannian or Finsler
Hui Liu, Jian Wang, Jingzhi Yan
In this article, we give a growth rate about the number of periodic orbits in the Franks type theorem obtained by the authors \cite{LWY}. As applications, we prove the following tw…
Kernel entropy estimation for long memory linear processes with infinite variance
Hui Liu, Fangjun Xu
Let be a long memory linear process with innovations in the domain of attraction of an -stable law . Assume that the linear process has…
Spin-split collinear antiferromagnets: a large-scale ab-initio study
Yaqian Guo, Hui Liu, Oleg Janson +3
It was recently discovered that, depending on their symmetries, collinear antiferromagnets can actually break the spin degeneracy in momentum space, even in the absence of spin-orb…
Equidistributed Closed Geodesics on Closed Finsler and Riemannian Surfaces
Hui Liu, Lei Liu
In this paper, we establish the existence of an equidistributed sequence of nondegenerate closed geodesics for generic Finsler, symmetric Finsler and Riemannian metrics on every cl…
A dichotomy result for closed characteristics on compact star-shaped hypersurfaces in
Huagui Duan, Hui Liu, Wenyan Ren
In this paper, we prove that if all closed characteristics on a compact non-degenerate star-shaped hypersurface in are elliptic, then either there exist exact…
