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.

Article Description
The associative algebras UTn(K) of the upper triangular matrices of order n play an important role in PI theory. Recently it was suggested that the Jordan algebra UJ2(K) obtained by UT2(K) has an extremal behaviour with respect to its codimension growth. In this paper we study the polynomial identities of UJ2(K). We describe a basis of the identities of UJ2(K) when the field K is infinite and of characteristic different from 2 and from 3. Moreover we give a description of all possible gradings on UJ2(K) by the cyclic group Z2 of order 2, and in each of the three gradings we find bases of the corresponding graded identities. Note that in the graded case we need only an infinite field K, charK≠2.
