en عمومى General پژوهشي Research paper <div style="text-align: justify;">In this article, we introduce and study Euler Catalan Riesz sequence spaces of nonabsolute type. We obtain some topological properties and Schauder basis of the newly formed sequence spaces. Moreover, we compute the &alpha;-, &beta;-, &gamma;-duals and characterize some matrix classes on this space. Finally, we prove that this sequence spaces are of Banach-Saks type p and has weak point property.</div> Catalan numbers, Euler mean of unit order, Matrix transformations, Riesz mean, α−, β−, γ−duals. 49 60 http://ijmsi.ir/browse.php?a_code=A-10-7275-1&slc_lang=en&sid=1 Kuldip Raj kuldipraj68@gmail.com 100319475328460012340 100319475328460012340 No School of Mathematics, Shri Mata Vaishno Devi University, Katra-182320, J&K, India Ayhan Esi aesi23@hotmail.com; ayhan.esi@ozal.edu.tr 100319475328460012341 100319475328460012341 Yes Malatya Turgut Ozal University, Engineering Faculty, Department of Basic Engineering Sciences (Math.Sect.) 440400, Malatya, Turkey Kavita Saini kavitasainitg3@gmail.com 100319475328460012342 100319475328460012342 No Department of Mathematics, Chandigarh University, Gharuan, Mohali-140413, Punjab, India
