摘要：
A new C*-algebra E + E. is established. It contains the large Hankel algebra N-G produced by all Toeplitz operators and Hankel operators. It is the proper algebra of B(H-2) and its essential commutant is obtained, which is generated by those Toeplitz operators that have symmetric continuous function symbols and compact operators.
