PhysTrackX: Open-Source Software for Kinematics Tracking for the Physics Laboratory
Isam Abdullah Balghari, Muhammad Sabieh Anwar
Video analysis software is a staple of the modern undergraduate physics laboratory, enabling students to extract quantitative kinematic data from real-world phenomena. In this pape…
Linearity and virtual poly-freeness of the fundamental group of plane curves of degree at most five
Shengkui Ye, Kejia Zhu
We prove that for any algebraic plane curve of degree at most , the fundamental group is linear and virtually polyfree. As a consequence, we…
Some questions related to free-by-cyclic groups and tubular groups
Xiaolei Wu, Shengkui Ye
We prove that a CAT(0) free-by-cyclic tubular group with one vertex is virtually special, but many of them cannot virtually act freely and cocompactly on CAT(0) cube complexes. Thi…
Splittings and poly-freeness of triangle Artin groups
Xiaolei Wu, Shengkui Ye
We prove that the triangle Artin group splits as a graph of free groups if and only if is greater than and even. This answers two questions of Jankiewi…
