TY - JOUR T1 - Some Results on the $p$-Weak Approximation Property in Banach Spaces AU - Keten Çopur, Ayşegül AU - Satar, Adalet PY - 2022 DA - December Y2 - 2022 DO - 10.33401/fujma.1099840 JF - Fundamental Journal of Mathematics and Applications JO - Fundam. J. Math. Appl. PB - Fuat USTA WT - DergiPark SN - 2645-8845 SP - 234 EP - 239 VL - 5 IS - 4 LA - en AB - In this study, some existing results dealing with the weak approximation property of Banach spaces are considered for the $p$-weak approximation property. Also, an observation on the bounded weak approximation and the $p$-bounded weak approximation properties is given. Moreover, the proof of the solution of the duality problem for the $p$-weak approximation property which exists in the literature is given in a shorter way as an alternative.
