A threshold method for financial networks and geometric scattering of agents
(Taylor and Francis Ltd., 2019)
Various filtering methods are applied to financial networks to overcome dimensionality problem of financial networks. In this study, we present a new threshold method based on Triangular Maximally Filtered Graph (TMFG) ...
Soft sets and soft rings
(Pergamon-Elsevier Science Ltd, 2010)
Molodtsov (1999) introduced the concept of soft sets in [1]. Then, Maji et al. (2003) defined some operations on soft sets in [2]. Aktas and Cagman (2007) defined the notion of soft groups in [3]. Finally, soft semirings ...
Topological structure of fuzzy soft sets
(Pergamon-Elsevier Science Ltd, 2011)
In this paper, the concept of fuzzy soft topology is introduced and some of its structural properties such as neighborhood of a fuzzy soft set, interior fuzzy soft set, fuzzy soft basis, fuzzy soft subspace topology are ...
A collocation method using Hermite polynomials for approximate solution of pantograph equations
