Nesterenko V.V. Various types of quasicontinuity and their

applications. The manuscript. Thesis for a degree of candidate of
Science (Ph. D.) in Physics and Mathematics, speciality 01.01.01 —
Mathematical Analysis. L’viv national university, L’viv, 2000.

Investigate conditions of quasicontinuous mappings on topological
spaces. A description of the set of quasicontinuity points is given and
the existence of continuity points of maps of two variables which are
horisontally quasicontinuous and quasicontinuous in the second variable
are obtained, and points of symmetrical quasicontinuity of
quasicontinuous maps. Besides a description of symmetrical
quasicontinuity and quasicontinuity are obtained.

Key words: quasicontinuous mappings, horisontal quasicontinuity,
symmetrical quasicontinuity, separate quasicontinuity
