We show that every space with a projectional skeleton has a projectional resolution of the identity and has a norming space with similar properties to .SIGMA.-spaces. As a corollary, we show that a Banach space is Plichko if and only if it has a commutative projectional skeleton.
Je ukázáno, že každý prostor s projekčním skeletonem má PRI. Jako důsledek je ukázáno, že Banachův prostor je Plichko, právě když má komutativní projekční skeleton.
