Periodic dimensions and some homological properties of eventually periodic algebras
Satoshi Usui
For an eventually periodic module, we have the degree and the period of its first periodic syzygy. This paper studies the former under the name \lq\lq periodic dimension\rq\rq. We…
Theoretical proposal of a revolutionary water-splitting photocatalyst: The monolayer of boron phosphide
