Non-Semisimple Quantum Invariants and TQFTs from Small and Unrolled Quantum Goups
Marco De Renzi, Nathan Geer, Bertrand Patureau-Mirand
We show that unrolled quantum groups at odd roots of unity give rise to relative modular categories. These are the main building blocks for the construction of 1+1+1-TQFTs extendin…
Energy-efficient Resource Allocation for Wirelessly Powered Backscatter Communications
Yinghui Ye, Liqin Shi, Rose Hu +1
In this letter, we consider a wireless-powered backscatter communication (WP-BackCom) network, where the transmitter first harvests energy from a dedicated energy RF source in the…
Heterogeneous Power-Splitting Based Two-Way DF Relaying with Non-Linear Energy Harvesting
Liqin Shi, Wenchi Cheng, Yinghui Ye +2
Simultaneous wireless information and power transfer (SWIPT) has been recognized as a promising approach to improving the performance of energy constrained networks. In this paper,…
Shortest Path Queries in Simple Polygons
Sang Won Bae, Haitao Wang
Let be a simple polygon of vertices. We consider two-point shortest path queries in . We build a data structure of size in time such that given any t…
Kuperberg and Turaev-Viro Invariants in Unimodular Categories
Francesco Costantino, Nathan Geer, Bertrand Patureau-Mirand +1
We give a categorical setting in which Penrose graphical calculus naturally extends to graphs drawn on the boundary of a handlebody. We use it to introduce invariants of 3-manifold…
General relativity as a biconformal gauge theory
James T Wheeler
We consider the conformal group of a space of dim n=p+q, with SO(p,q) metric. The quotient of this group by its homogeneous Weyl subgroup gives a principal fiber bundle with 2n-dim…
