A function f defined on a subset of a topological group is quasi-slowly (respectively, Delta-quasi-slowly) oscillating continuous if it preserves quasislowly (respectively, Delta-quasi-slowly) oscillating sequences, i.e. (f (x(n))) is quasi-slowly (respectively, Delta-quasi-slowly) oscillating whenever (x(n)) is. We study these kinds of continuities, and investigate relations with statistical continuity, lacunary statistical continuity, and some other types of continuities in metrizable topological groups.
