On some properties of $I$-approximate Dini derivatives

Rok, strany: 2002, 79 - 88

E. Łazarow and W. Wilczyński defined in [E. Ł azarow: On the Baire class of $cal I$-approximate derivatives, Radovi Matematicki 5 (1989), 15–27] $cal I$-approximate Dini derivatives of a real function of a real variable, having (locally) the Baire property. In the paper, $cal I$-approximate Dini derivatives of an arbitrary real function (without assuming its Baire property) are considered and some properties of the $cal I$-approximate Dini derivatives are presented.
