Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We fully solve the quantum geometry of Zn as a polygon graph with arbitrary metric square-lengths on the edges, finding a-preserving quantum Levi-Civita connection which is unique for n ≠ 4. As a first application, we numerically compute correlation functions for Euclideanised quantum gravity on Zn for small n.We then study an FLRWmodel on R × Zn, finding the same expansion rate as for the classical flat FLRW model in 1 + 2 dimensions.We also look at particle creation on R × Zn and find an additional m = 0 adiabatic no particle creation expansion as well as the particle creation spectrum for a smoothed step expansion.
