MATRIX TRANSFORMATIONS OF c0(p,s), 100(p,s) and l(p,s) INTO Q
Abstract
Necessarv and sufficicnt condi , tions haYe been cstablished for an infini te matrix A= (͙k) to transform c0(p,s) , f.00(p,s) and ((p,s) into Q (semipcriodic scqucnces space), \vhere c0(ps) and e00( p,s) the set of aJJ complex sequenccs X= (xk) such that limk (kslxkıPk)=O and supk (k-slxkıPk)lt;oo, respectively., p = (PJç) strictly positive nunıbcrs anJ s; O is a real number
