Relativization of Star-C-Hurewicz Property in Topological Spaces
In this paper, we introduced relatively star- C -Hurewicz property in topological spaces following the approach of Bonanzinga and Pansera (Acta Math Hungar 117(3):231–243, 2007) and Guido and Kočinac (Quest Answ Gen Topol 19:107–114, 2001). A subspace A of a topological space X is said to have relat...

Zusammenfassung: | In this paper, we introduced relatively star-
C
-Hurewicz property in topological spaces following the approach of Bonanzinga and Pansera (Acta Math Hungar 117(3):231–243, 2007) and Guido and Kočinac (Quest Answ Gen Topol 19:107–114, 2001). A subspace
A
of a topological space
X
is said to have relatively star-
C
-Hurewicz property in
X
(in short,
RSCH
) or relatively star-
C
-Hurewicz subspace of
X
if for each sequence
U
n
:
n
∈
ω
of open covers of
X
there is a sequence
A
n
:
n
∈
ω
of countably compact subsets of
X
such that
x
∈
A
belongs to
S
t
(
A
n
,
U
n
)
for all but finitely many
n
. It is shown that relatively star-
C
-Hurewicz property is hereditary. In this manner, we obtained relationships of relatively star-
C
-Hurewicz property with other existing Hurewicz properties in the literature. |
