The four maximal sets of additive quantum numbers and related fine gradings of the Lie algebra sl(3,C) are described in detail. The quantum numbers are determined by a grading of the Lie algebra, fine ...

In this work it is shown that, in contrast to the strong and electromagnetic theories, additive conserved numbers (such as lepton, aromatic and another numbers) and gamma-5 anomaly do not appear in ...

Our goal in this study was to collect in a systematic way empirical data about the scope and the nature of upper elementary school pupils' difficulties with modeling and solving nonroutine additive ...
