Аннотация:
In the literature,
$\mathcal{I}$-convergence (or convergence in
$\mathcal{I}$) was first introduced in
[11].
Later related notions of
$\mathcal{I}$-sequential topological space and
$\mathcal{I}^*$-sequential topological space were introduced and studied. From the definitions it is clear that
$\mathcal{I}^*$-sequential topological space is larger(finer) than
$\mathcal{I}$-sequential topological space. This rises a question: is there any topology (different from discrete topology) on the topological space
$\mathcal{X}$ which is finer than
$\mathcal{I}^*$-topological space? In this paper, we tried to find the answer to the question.
We define
$\mathcal{I}^{\mathcal{K}}$-sequential topology for any ideals
$\mathcal{I}$,
$\mathcal{K}$ and study main properties of
it. First of all, some fundamental results about
$\mathcal{I}^{\mathcal{K}}$-convergence of a sequence in a topological space
$(\mathcal{X} ,\mathcal{T})$ are derived. After that,
$\mathcal{I}^{\mathcal{K}}$-continuity and the subspace of the
$\mathcal{I}^{\mathcal{K}}$-sequential topological space are investigated.
