Homological Invariants of Left and Right Serial Quiver Algebras
Ruoyu Guo
We investigate the relationship between the delooping level (dell) and the finitistic dimension of left and right serial quiver algebras. These 2-syzygy finite algebras have finite…
A Novel Loss Function for Deep Learning Based Daily Stock Trading System
Ruoyu Guo, Haochen Qiu, Xuelun Hou
Making consistently profitable financial decisions in a continuously evolving and volatile stock market has always been a difficult task. Professionals from different disciplines h…
Symmetry of Derived Delooping Level
Ruoyu Guo
The finitistic dimension conjecture is closely connected to the symmetry of the finitistic dimension. Recent work indicates that such connection extends to one of its upper bounds,…
Derived delooping levels and finitistic dimension
Ruoyu Guo, Kiyoshi Igusa
In this paper, we develop new ideas regarding the finitistic dimension conjecture, or the findim conjecture for short. Specifically, we improve upon the delooping level by introduc…
Spectral decimation of the magnetic Laplacian on the Sierpinski gasket: Solving the Hofstadter-Sierpinski butterfly
Joe P. Chen, Ruoyu Guo
The magnetic Laplacian (also called the line bundle Laplacian) on a connected weighted graph is a self-adjoint operator wherein the real-valued adjacency weights are replaced by un…
