For this aim, the notions of $$\delta^{*}$$-open, $$\delta$$-$$\delta^{*}$$-$$\alpha$$-open, $$\delta$$-$$\delta^{*}$$-preopen, $$\delta$$-$$\delta^{*}$$-semiopen, $$\delta$$-$$\delta^{*}$$-$$b$$-open, $$\delta$$-$$\delta^{*}$$-$$\beta$$-open, $$\delta^{*}$$-$$\delta$$-$$\alpha$$-open, $$\delta^{*}$$-$$\delta$$-preopen, $$\delta^{*}$$-$$\delta$$-semiopen, $$\delta^{*}$$-$$\delta$$-$$b$$-open, $$\delta^{*}$$-$$\delta$$-$$\beta$$-open, $$\delta^{*}$$-$$\alpha$$-open, $$\delta^{*}$$-preopen, $$\delta^{*}$$-semiopen, $$\delta^{*}$$-$$b$$-open and $$\delta^{*}$$-$$\beta$$-open sets are introduced. Properties and the relationships of $$\delta^{*}$$-open sets are... investigated. Finally, the relationships between these sets and the related concepts are investigated.
