The first paper in which the notion of polynomial identity appears that I know of is a 1922 article of M. Dehn [D], where his goal was to generalize Pappus’ Theorem from projective geometry. (His program was carried out by S.A. Amitsur in 1966 [A4] using rational identi...

UDC 512.5 We determine the relative rank of the semigroup ${\scr T }(X,Y)$ of all transformations on a finite chain $X$ with restricted range $Y\subseteq X$ modulo the set ${\scr OP }(X,Y)$ of all orientation-preserving transformations in ${\scr T }(X,Y).$ Moreover, we ...

The Earth’s surface is a rigid lower boundary of the atmosphere. Due to this, a boundary layer exists in the wind velocity field or in other meteorological elements. Because the air flow is generally turbulent, this is a turbulent boundary layer rather than molecular. N...
