We give the definition of (τ1,τ2)-semi open soft (resp. (τ1,τ2)-pre open soft, (τ1,τ2)-α-open soft, (τ1,τ2)-β-open soft, (τ1,τ2)'-semi open soft, (τ1,τ2)'-pre open soft, (τ1,τ2)'-α-open soft, (τ1,τ2)'-βopen soft) set via two soft topologies.

文摘In this paper, we study the concept of soft sets which is introduced by Molodtsov [5]. We give the definition of (τ1,τ2)-semi open soft (resp. (τ1,τ2)-pre open soft, (τ1,τ2)-α-open soft, (τ1,τ2)-β-open soft, (τ1,τ2)'-semi open soft, (τ1,τ2)'-pre open soft, (τ1,τ2)'-α-open soft, (τ1,τ2)'-βopen soft) set via two soft topologies. Also we introduce (τ1,τ2)-regular open soft and ESDC on two soft topologies. The aim of this paper is to investigate properties of some mixed soft operations and characterizations of ESDC. Finally, we study τ2-ESDC soft topologies τ1.
