Here , we shall first be concerned with certain special examples of convolutions which map H into H , which belong to the algebra A , and which have an integral representation in one of the two forms ( 18 ) ( S * q ) ( 3 ) = S ...

This observation enables us to define the integral ( 21 ) f ( s ) = Se - ts ' ) ( dt ) , = - ) , 8 € RN RN which will be used presently . The translation qe , however , is not compact valued , and we proceed as follows .
