Abstract

In this paper we use some cardinal functions introduced in [3], [5] and [1], and the technique of elementary submodels to generalize some cardinal inequalities. Also, we introduce the cardinal functions, denoted by (γ,θ)−wLθ and Uθ⁎, and we prove that: |X|≤2(γ,θ)−wLθ(X)χ(X), for any T1-space X with Uθ⁎(X)≤ω.
