Decoding of orbit codes
(Işık University Press, 2019)Subspace codes have an important role to correct errors and erasures for random network coding. Orbit codes are a family of constant dimension subspace codes and they are interesting for their error correction. In this ... -
Decomposition of tensor product of complete graphs into cycles and stars with four edges
(Işık University Press, 2023-04)In this paper, we prove that the necessary conditions are sufficient for the existence of a decomposition of tensor product of complete graphs into cycles and stars with four edges. -
Degree based topological indices of line graph of a cayley tree Γᵏn
(Işık University Press, 2023-01)Several topological indices and their chemical applicability have been studied in chemical graph theory. Some of the degree based topological indices, namely Zagreb index, Modified Zagreb index, Randić index, Atom-bond ... -
Degree equivalence graph of a graph
(Işık University Press, 2020)Given a set S and an equivalence relation R on S, one can define an equivalence graph with vertex set S. Given a graph with vertex set V , we can define an equivalence relation on V using the concept of degree of a vertex ... -
Degree of approximation by product (Ṅ, pn, qn)(E, q) summability of fourier serıes of a signal belonging to Lip(α, r)-class
(Işık University Press, 2019)Approximation of periodic functions by different linear summation methods have been studied by many researchers. Further, for sharpening the estimate of errors out of the approximations several product summability methods ... -
Degree of approximation in the generalized Lipschitz class via (E, q)a- product summability means of fourier series
(Işık University Press, 2020)Dealing with degree of approximation of Fourier series of functions of Lipchitz classes, some results have been established by Nigam [15] and Misra et al. [17]. In this paper, we have established a new theorem based on (E, ... -
‘Del’ relation and parallelism in fuzzy lattices
(Işık University Press, 2022)The notions of ‘del’ relation, a neutral element and parallelism from lattice theory are introduced in a fuzzy lattice and their properties are obtained. -
Denumerably many positive solutions for rl-fractional order bvp having denumerably many singularities
