Title: On some analytical index formulas related to 
       operator-valued symbols 
   
Author: Grigori Rozenblum (Chalmers Univ. of Technology, Goteborg, Sweden)

Abstract: 
  For several classes of pseudodifferential operators with 
  operator-valued  symbol analytic index formulas are found.  
  The common feature is that  usual index formulas are not 
  valid for these operators.  Applications are given to 
  pseudodifferential operators on singular manifolds.
