Engineering College, Guntur (District) Andhra Pradesh, India. 4 Department of Mathematics, Koneru Lakshmaiah Education Foundation, Vaddeswaram, A.P., India ---------------------------------------------------------------------***---------------------------------------------------------------------- ABSTRACT - In this article we introduce and study Weakly minimal closes sets of Type1-R0 spaces, Weakly minimal g-closed sets of Type1-R0 spaces, Weakly minimal closed sets of Type1-i-R0 spaces, Weakly minimal closed sets of Type1-d-R0 spaces, Weakly minimal closed sets of Type1- b-R0 spaces, and also discuss the inter-relationships among separation properties along with several counter examples. Key Wards: minimal open sets, minimal g-open sets, minimal open sets of Type1, minimal g-open set of Type1. 1. INTRODUCTION. L.Nachbin[6] Topology and order, D.Van Nostrand Inc., Princeton, New Jersy studied increasing [resp. decreasing, balanced] open sets in 1965. K. Bhagya Lakshmi, J. Venkateswara Rao[13] studied W-R0 Type spaces in topological ordered spaces in 2014. G.Venkareswarlu, V.Amarendra Babu, and M.K.R.S Veera kumar [11] introduced and studied minimal open sets of Type1 sets, minimal g-open sets of Type1 sets in 2016. G.Venkateswarlu, V.Amarendra Babu, K. Bhagya Lakshmi and V.B.V.N. Prasad [14] studied W-C0 Spaces in 2019. In this article we introduce new separation axioms of type Weakly- minimal closed sets Type1-R0 spaces, Weakly minimal g-closed sets of Type1-R0 spaces, Weakly minimal g- closed sets of Type1-i-R0 spaces, Weakly minimal g- closed sets of Type1-d-R0 spaces, Weakly minimal g- closed sets of Type1-b-R0 spaces, and discuss the inter-relationships among separation properties along with several counter examples. 2. PRELIMINARIES. DEFINITION 2.1[11]: In a topological space (X, Ƭ), an open sub set U of X is called a minimal open sets of Type! If ∃ at least one non-empty closed set F such that F⊆U or U = Ф. DEFINITION 2.2[11]: In a topological space (X, Ƭ), an open sub set U of X is called a minimal g- open sets of Type! If ∃ at least one non-empty g- closed set F such that F⊆U or U = Ф. 3. MAIN RESULT: Now we state and prove our first main result. Before that we first introduce the following definitions and notations. Note: The collections of all increasing Weakly-minimal closed sets of Type1, increasing Weakly-minimal g-closed sets Type1 is denoted by W-i-mi cl(Z, T1), W-i-mi-gcl(Z, T1). [resp. decreasing and balanced is denoted by W-d-mi cl (Z, T1), W-d-mi-gcl(Z, T1), W-b-mi cl(Z, T1), W-b-mi-gcl (Z, T1)]. Topological ordered space is denoted by TOS, Weakly-Minimal closed sets of Type 1, Weakly-Minimal g-closed sets of Type 1, set is denoted by W- mi cl(Z, T1), W-mi-gcl (Z, Τ1) and α-closed, β-closed, Ψ-closed is denoted by αcl,βcl, Ψcl. WE INTRODUCE THE FOLLOWING DEFINITIONS: DEFINITION 3.1: In a topological space (Z, Ƭ), a non empty closed subset F of Z is called a minimal closed sets of Type1 if ∃ at least one nom-empty open set U such that F⊆U or U=Z. DEFINITION 3.2: In a topological space (Z, Ƭ), a non empty g- closed subset F of Z is called a minimal g- closed sets of Type1 if ∃ at least one nom-empty g- open set U such that F⊆U or U=Z. DEFINITION 3.3: A space (Z, Ƭ) is called a minimal closed sets of Type1 R0-space if mi cl{x} contained in G where G is Minimal closed sets of Type1( brifly mi cl{x}) and xϵGϵƬ DEFINITION 3.4: A space (Z, Ƭ) is called a minimal g- closed sets of Type1 R0-space if mi-gcl{x} contained in G where G is Minimal g-closed sets of Type1( brifly mi-gcl{x}) and xϵGϵƬ DEFINITION 3.5: A space (Z, Ƭ) is called a minimal g- closed sets of Type1 α-R0-space if for xϵGϵmi-g-O(Z, Ƭ) αmi-gcl{x} contained in G where G is Minimal g-closed sets of Type1( brifly mi-gcl{x}) and xϵGϵƬ DEFINITION 3.6: A space (Z, Ƭ) is called a minimal g- closed sets of Type1 Ψ-R0-space if for xϵGϵmi-g-O(Z, Ƭ) Ψmi-gcl{x} contained in G where G is Minimal g-closed sets of Type1( brifly mi-gcl{x}) and xϵGϵƬ

That implies the intersection of bΨcl{x} contained in d- mi- gcl{x}. But the intersection of d-mi-gcl{x} empty set x∈Z. we get the intersection of bΨcl{x} is empty set x∈Z Hence (Z, Τ) is W-bΨR0 space. EXAMPLE 3.74: Let Z={ ζ₁, δ₂, Ω₃ } and T= { Ф, Z, {ζ₁}, {ζ₁, Ω₃} }. ≤7 = {(ζ₁, ζ₁), (δ₂, δ₂), (Ω₃, Ω₃), (δ₂, ζ₁) }. mi-gcl(Z, Τ1) are Ф, Z, {ζ₁}, {δ₂, Ω₃} d-mi-gcl(Z, Τ1) are Ф,Z, {δ₂, Ω₃] Ψcl sets are Ф, Z, {δ₂}, {Ω₃}, {δ₂, Ω₃} bΨcl sets are Ф, Z, {Ω₃} d-mi-gcl{ζ₁} is Z bΨcl{ζ₁} is Z d-mi-gcl{δ₂} is {δ₂, Ω₃} bΨcl{δ₂} is Z d-mi-gcl{Ω₃} is {δ₂, Ω₃} bΨcl{Ω₃} is {Ω₃} The intersection of d-mi-gcl{x} is {δ₂, Ω₃} The intersection of bΨcl{x} is [Ω₃} not equal to {δ₂, Ω₃} bΨcl{ζ₁} is Z bΨcl{δ₂} is Z bΨcl{Ω₃} is {Ω₃} The intersection of bΨcl{x} is [Ω₃} not equal to {δ₂, Ω₃} The following diagrams shows the above results.
