On trigonometric-like decompositions of functions with respect to the cyclic group of order n
The cyclic group labeled family of quasi-projection operators is used for investigation of decomposition of functions with respect to the cyclic group of order n . Series of new identities thus arising are demonstrated and new perspectives for further investigation are indicated as for example in the case of q-extended special polynomials.

Maximal ideal space of a commutative coefficient algebra
The basic notion of the article is a pair (A,U), where A is a commutative C*-algebra and U is a partial isometry such that mapping U()U* is an endomorphism of A and U*U belongs to A. We give a description of the maximal ideal space of the smallest coefficient C*-algebra of the algebra C*(A,U) generated by the system (A,U).
