We give a short survey of results on ideal convergence with some
applications. In particular, we present a contribution of mathematicians from Łódź to these investigations during the recent 16 years.

We prove in this paper that any maximal, with respect to inclusion, subset of N – the family of all increasing sequences of positive integers –
possessing the harmonic series property has the cardinality of the continuum.
Moreover, we prove that for any countable (infinite) set
exists an "orthogonal" family such that it hold some facts. All facts are proved constructively, by using the...

In this paper, the Hyers-Ulam stability of the Volterra integrodifferential equation and the Volterra equation on the finite interval [0, T], T > 0, are studied, where the state x(t) take values in a Banach space X.
