Abstract
It is shown that every uncountable symmetric basic set in an F-space with a symmetric basis is equivalent to a basic set generated by one vector. We apply this result to investigate the structure of uncountable symmetric basic sets in Orlicz and Lorentz spaces.
Keywords
symmetric basis, Orlicz sequence spaces, Lorentz sequence spaces
