Nonlinear Functional Difference Equations with Applications

[...]we considered that 17 of the articles have to be considered in wider mathematical circles, being published in this journal in a special volume. In the paper titled "Characterizations of strongly paracompact spaces" the author proves that a countably paracompact normal space (a perfectly normal space or a monotonically normal space) is strongly paracompact if and only if every increasing open cover of the space has a star-countable open refinement. [...]it is shown that a space is linearly D, provided that every increasing open cover of the space has a point-countable open refinement.
