The intuitionistic hesitant fuzzy set (IHFS) is an enriched version of sets (HFSs) that can cover both (FSs) and (IFSs). By assigning membership non-membership grades as subsets [0, 1], the IHFS model handle situations more proficiently. Another related theory pair analysis (SPA), which considers certainties uncertainties a cohesive system represents them from three aspects: identity, discrepancy, contrary. In this article, we explore suitability combining SPA theories in multi-attribute...

Assessment specialists (experts) are sometimes expected to provide two types of information: knowledge rating domains and the performance objects (called confidence levels). Unfortunately, results previous information aggregation studies cannot be properly used combine categories data covered above. Additionally, a significant range symmetric/asymmetric events structures frequently included in implementation process or practical use fuzzy systems. The primary goal current study was cubic...

The theory of spherical linear Diophantine fuzzy sets (SLDFS) boasts several advantages over existing set (FS) theories such as Picture (PFS), (SFS), and T-spherical (T-SFS). Notably, SLDFS offers a significantly larger portrayal space for acceptable triplets, enabling it to encompass wider range ambiguous uncertain knowledge data sets. This paper delves into the regularity graphs (SLDFGs), establishing their fundamental concepts. We provide geometrical interpretation SLDFGs within context...

We provide a possible way of constructing new kinds manifolds which we will call Partially Negative Dimensional Product manifold (PNDP-manifold for short). In particular PNDP-manifold is an Einstein warped product special kind, where the base-manifold $B$ Remannian (or pseudo-Riemannian) product-manifold $B=Π_{i=1}^{q'}B_i \times Π_{i=(q'+1)}^{\widetilde q} B_i$, with $Π_{i=(q'+1)}^{\widetilde B_i$ Einstein-manifold, and fiber-manifold $F$ derived-differential-manifold (i.e., form: smooth...

We introduce a new geometric/topological approach to the emerging braneworld scenario in context of D-branes using partially negative dimensional product (PNDP) manifolds. The working hypothesis is based on fact that orientability PNDP manifolds can be arbitrary, and starting from this, we propose gravitational interaction derive naturally non-orientability. According this hypothesis, show topological defects emerge non-orientability they identified as at macroscopic level. In other words,...

Recently, PNDP-manifolds have been introduced, and these shown to be useful in applicative aspects especially the field of cosmology, introducing a new geometric/topological approach concept “emerging space”. However, applications considered so far concern only trivial flat PNDP-manifolds. Therefore, we show existence non-Ricci-flat solutions for with positive “virtual” dimension which hyperbolic [Formula: see text]-manifold. Based on this, advanced an hypothesis, accompanied by some open...
