Three-valued logics belong to a family of nonclassical logics that started to flourish in the 1920s and 1930s, following the work of ( Lukasiewicz, 1920), and earlier insights coming from Frege and Peirce (see (Frege, 1879), (Frege, 1892), (Fisch and Turquette, 1966)). All of them were moved by the idea that not all sentences need be True or False, but that some sentences can be indeterminate i...

Many of the spatial attributes in our everyday contexts are vague – imprecise and indeterminate. Imprecision is intrinsic (such as indefinite boundaries for certain regions) or situational (such as imprecise location information due to ignorance or inherent errors/imprecision in measuring devices). Even though qualitative representations have an intrinsic facility to handle indefinite and impre...

Let $\mathbb{F}_p$ be a finite field and $u$ be an indeterminate. This article studies $(1-2u^2)$-constacyclic codes over the ring $\mathbb{F}_p+u\mathbb{F}_p+u^2\mathbb{F}_p$, where $u^3=u$. We describe generator polynomials of this kind of codes and investigate the structural properties of these codes by a decomposition theorem.

This paper introduces sector-specific externalities in the Heckscher–Ohlin twocountry dynamic general equilibrium model to show that indeterminacy of the equilibrium path in the world market can occur. Under certain conditions in terms of factor intensities, there are multiple equilibrium paths from the same initial distribution of capital in the world market, and the distribution of capital in...

We consider indeterminate rational moment problems on the real line with their associated orthogonal rational functions. There exists a Nevanlinna type parameterization relating to the problem, with associated Nevanlinna matrices of functions having singularities in the closure of the set of poles of the rational functions belonging to the problem. We prove that the growth at the isolated singu...

The Palaeocene sediment of the Tiruchirapalli area shows presence of some elements of geniculate and non-geniculate coralline Algae. Four coralline algal species are recorded from this Formation (Thanetian age). Two of the described species belong to Sporolithon. Of the remaining two, one is assigned to Coralline, while the other one is indeterminate, being referred to the subfamily Melobesioid...

As a significant business activity, merger and acquisition (M&A) generally means transactions in which the ownership of companies, other business organizations or their operating units are transferred or combined. In a typical M&A procedure, M&A target selection is an important issue that tends to exert an increasingly significant impact on different business areas. Although some research works...

As a neutrosophic number, which consists of a determinate part and an indeterminate part, can more easily and better express incomplete and indeterminate information that exists commonly in real situations, the main purposes of this paper are to provide a neutrosophic number tool for group decision-making problems with indeterminate information under a neutrosophic number environment and to dev...
