Metric Options: CountsSelecting 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.

Lecture / Presentation Description
Professor Ian Anderson has developed software for the computer classification of lower dimensional Lie algebras. For computer classification of space-times, the main objects of study in Einstein's theory of general relativity, more is needed. In this presentation I will describe our new software for the classification of Lie algebra-subalgebra pairs. This software is the key tool and an integral part of a larger scheme to determine the equivalence of space-times with symmetry. These equivalences come in the form of diffeomorphisms and can only be computed once an equivalence of particular Lie algebra-subalgebra pairs has been found. This larger scheme will be explained to demonstrate the importance of the new software.
