Localization C∗-algebras and index pairing
Kasparov KK -theory for a pair of C ∗ -algebras ( A , B ) can be formulated equivalently in terms of the K -theory of Yu’s localization algebra by Dadarlat-Willett-Wu. We investigate the pairings between K -theory K j ( A ) and the two notions of KK -theory which are Kasparov KK -theory K K i ( A ,...

Summary: | Kasparov
KK
-theory for a pair of
C
∗
-algebras
(
A
,
B
)
can be formulated equivalently in terms of the
K
-theory of Yu’s localization algebra by Dadarlat-Willett-Wu. We investigate the pairings between
K
-theory
K
j
(
A
)
and the two notions of
KK
-theory which are Kasparov
KK
-theory
K
K
i
(

)
and the localization algebra description of
K
K
i
(

)
and show that the two pairings are compatible. |
