Inhalt:
A special class of fix-free codes called γ-expandable fix-free codes is defined. An exact sufficient condition for the existence of a γ-expandable D-ary fix-free code is derived. Using the concept of γ-expandability we present some Kraft-type sufficient conditions for the existence of D-ary fix-free codes.
