摘要：We continue the study by the ffrst author on isometric and unitary Toeplitz + Hankel operators [22]. We give a complete description of the symbols of unitary (T+H)-operators. By factorizing a large class of isometric (T+H)-operators as products of Toeplitz operators and unitary (T+H)-operators, we ffnd the spectrum of these isometries. Explicit examples of isometric and unitary (T+H)-operators are presented to illustrate that these operators are interesting and are worthy of further investigation.
