O článku:

A function $f: Bbb R o Bbb R$ is said to be bilaterally quasicontinuous at a point $x$ if for every $δ>0$ and for every neighbourhood $V$ of $f(x)$ there exist open nonempty sets $G₁subset (x-δ, x)cap f^-1(V)$ and $G₂subset (x, x+δ)cap f^-1(V)$. Some possibilities to define a bilateral quasicontinuity for functions defined on metric or topological spaces are given.
