Numerical invariants of identities of unital algebrasRepovš, Dušan (Avtor) Zaicev, Mikhail (Avtor) codimensionexponential growthfractional PI-exponentnon-associative unital algebrapolynomial identityWe study polynomial identities of algebras with adjoined external unit. For a wide class of algebras we prove that adjoining external unit element leads to increasing of PI-exponent precisely to 1. We also show that any real number from the interval ▫$[2,3]$▫ can be realized as PI-exponent of some unital algebra.20152019-09-30 09:57:39Članek v reviji111407UDK: 512.552ISSN pri članku: 0092-7872DOI: http://dx.doi.org/10.1080/00927872.2014.924130COBISS_ID: 17339737OceCobissID: 25249792sl
