Continuity of Superposition Operators on the Double Sequence Spaces L-p
Sagir, Birsen; Gungor, Nihan (Univ Nis, Fac Sci Math, 2015)In this paper, we define the superposition operator P-g where g : N-2 x R -> R by P-g ((x(ks))) = 1 (k, s, x(ks)) for all real double sequence (x(ks)). Chew & Lee [4] and Petranuarat & Kemprasit [7] have characterized P-g ... -
Continuity of Superposition Operators on the Double Sequence Spaces of Maddox L(p)
Gungor, Nihan; Sagir, Birsen (Springer International Publishing Ag, 2017)Petranuarat and Kemprasit (Southeast Asian Bull Math 21: 139-147, 1997) characterized continuity of the superposition operator acting from the sequence space l(p) into l(q) where 1 <= p, q < infinity. Sagir and Gungor ... -
LOCALLY BOUNDEDNESS AND CONTINUITY OF SUPERPOSITION OPERATORS ON DOUBLE SEQUENCE SPACES C-r0
Sagir, Birsen; Gungor, Nihan (Eudoxus Press, Llc, 2015)Let R be set of all real numbers, N be the set of all natural numbers and N-2 = N x N. In this paper, we define the superposition operator P-g where g : N-2 x R -> R by P-g ((x(ks))) = g (k, s, x(ks)) for all real double ... -
Non-Newtonian Comment of Lebesgue Measure in Real Numbers
Duyar, Cenap; Sagir, Birsen (Hindawi Ltd, 2017)We would like to generalize to non-Newtonian real numbers the usual Lebesgue measure in real numbers. For this purpose, we introduce the Lebesgue measure on open and closed sets in non-Newtonian sense and examine their ... -
A note on weighted Sobolev algebras L-omega(1)(R-d) boolean AND W-k(p)(R-d)
Gungor, Nihan; Sagir, Birsen (Ramanujan Mathematical Soc, 2015)Let 1 <= p < infinity and omega be Beurling's weight function on R-d. In this article, we demonstrate some harmonic properties of Sobolev space W-k(p)(R-d) which consists of all functions on R-d whose weak derivatives up ... -
On a new class Wp,q of Segal algebras
Sagir, Birsen; Duyar, Cenap (Eudoxus Press, Llc, 2011)The aim of this paper is to define a new class of Segal algebras, denoted by W-p,W-q, and to examine their some properties. -
On Characterization of Non-Newtonian Superposition Operators in Some Sequence Spaces
Sagir, Birsen; Erdogan, Fatmanur (Univ Nis, Fac Sci Math, 2019)In this paper, we define a non-Newtonian superposition operator P-N(f) where f : N x R(N)(alpha) -> R(N)(beta) by P-N(f) (x) = (f (k, x(k)))(k=1)(infinity) for every non-Newtonian real sequence x = (x(k)). Chew and Lee [4] ... -
On the Function Sequences and Series in the Non-Newtonian Calculus
Sagir, Birsen; Erdogan, Fatmanur (Editura Bibliotheca-Bibliotheca Publ House, 2019)The purpose of this study is to examine the function sequences and series in the non-Newtonian real numbers. Firstly, the information about the studies that are done until today and the application areas, was briefly given. ... -
SOME ASPECTS OF L-v(q) (R-d) boolean AND W-k(p,w) (R-d)
Gungor, Nihan; Sagir, Birsen (Univ Miskolc Inst Math, 2015)Let 1 <= q; p < infinity and v,w be Beurling's weight functions on R-d. In this article we deal with harmonic properties of intersection space A(k,v,w)(q,p) (R-d) = L-v(q) (R-d) boolean AND W-k(p,w) (R-d) defined by aid ...
