A class of integral operators from lebesgue spaces into harmonic bergman-besov or weighted bloch spaces
(Hacettepe University, 2021)We consider a class of two-parameter weighted integral operators induced by harmonic Bergman-Besov kernels on the unit ball of Rn and characterize precisely those that are bounded from Lebesgue spaces Lp? into harmonic ... -
Bounds for distance between eigenvalues of boundary value problems with retarded argument
(De Gruyter, 2019)In this study we are concerned with spectrum of boundary value problems with retarded argument with discontinuous weight function, two supplementary transmission conditions at the point of discontinuity, spectral and ... -
Pointwise Bi-Slant Submersions From Cosymplectic Manifolds
(2020)We introduce pointwise bi-slant submersions from cosymplectic manifolds onto Riemannian manifolds as a generalization of anti-invariant, semi-invariant, semi-slant, hemi-slant, pointwise semi-slant, pointwise hemi- slant ... -
Spectral properties of boundary-value-transmission problems with a constant retarded argument
(TUBITAK, 2019)In this work, spectra and asymptotics of eigenfunctions of a generalized class of boundary value problems with constant retarded argument are obtained. Contrary to previous works in the literature, the problem has nonclassical ... -
On a subclass of the generalized janowski type functions of complex order
(Hacettepe University, 2020)In this paper, we introduce the class ?R? b (?, ?, ?, A,B) of generalized Janowski type functions of complex order defined by using the Ruscheweyh derivative operator in the open unit disc D = {z ? ?: |z| < 1}. The bound ... -
A note on distributivity of the lattice of L-ideals of a ring
(Hacettepe University, 2019)Many studies have investigated the lattice of fuzzy substructures of algebraic structures such as groups and rings. In this study, we prove that the lattice of L-ideals of a ring is distributive if and only if the lattice ... -
Maximal arcs, codes, and new links between projective planes of order 16
(Electronic Journal Of Combinatorics, 2020)In this paper we consider binary linear codes spanned by incidence matrices of Steiner 2-designs associated with maximal arcs in projective planes of even order, and their dual codes. Upper and lower bounds on the 2-rank ... -
Generalized logistic equation method for Kerr law and dual power law Schrodinger equations
(Springer, 2020)The Kerr law and dual power law Schrodinger equations for obtaining optical soliton solutions are studied. In this paper, we investigate these equations via generalized logistic equation method. These various kinds of ... -
Pointwise slant submersions from almost product Riemannian manifolds
(Taru Publications, 2020)In this paper, we investigate pointwise slant submersions from almost product Riemannian manifolds onto Riemannian manifolds. We obtain some characterizations for such a submersion. Also we find curvature relations between ... -
