For this we search coefficients A J, A 2 , ••• , Ak such that ll=AIUJ+A2U2+· .. +AkUk. Using the formulas (17), (17') and (18) we obtain the following triangle system for the coefficients from the requirement II * Uk = Uk: u a a u AkCk= 1, Ak_1Ck+AkCk':':'j =0, 26 CHAPTERl These simultaneous equations always have a solution for AI' A2 , ••• , A k • Thus the existence of an element Il O! with Il *1l=1l is proved. Then U*Uj=U J for each j, with lsj

The romplete multiplier relation M(x*y)=(Mx)*y follows from Lemma 1, since the convolution * is assumed to be annihilators-free. e. it belongs to the commutant of L. 1 the closed graph theorem implies con~uity of M. 0 Cor 0 II a r y 1. All annihilators-free and continuous convolutions of an endomorphism of a Frecker space witk a cyclic element have the same multiplier ring. In fact, this multiplier ring is the commutant of L in [t.

If * is a continuous convolution in a Frechet spare of a linear right inverse operator L: [t -+ XD C x of a right-invertible operator D: XD - > [t with a cyclic element in [t, and with a convolutional representation Lx = r * x, then every continuous endomorphism M: -+ [t, which commutes with L in [t, admits a representation of the form x x (31) Mx=D(m*x), m=Mr.

This shows that T: X -4 i is an isomorphism not only of linear spaces, but of algebras too. Therefore, if one of the algebras (x, *) and (i. ;) is annihilators-free, then the other is annihilators-free too. eo roll a r y 2.

If the image-space T(x) of under T is closed with respect to the operation ;;;, then operation (20) is a convolution of the operator L = T-ILT in X.
