Abstract:
The notion of index for arbitrary real factors is introduced and investigated. The main tool in our approach is the reduction of real factors to involutive $*$-antiautomorphisms of their complex enveloping von Neumann algebras. Similarly to the complex case the values of the index for real factors are calculated.
Keywords and phrases:
$W^*$-algebras, real factor, index of subfactor.
