چکیده

In this paper, we introduce the notions of (∈,∈ ∨ q)-N -ideals and (γ, δ)-N -ideals of subtraction algebras, which are generalization of N -ideals. Some characterization for these generalized N -ideals are derived. Also, we introduce the notions of (∈,∈ ∨ q)-N -ideals and N -ideals with thresholds of subtraction algebras. The characterization of N -ideals with thresholds by their closed (f, t)-cut ideals over the subtraction algebras X is also established. c ©2015 World Academic Press, UK. All rights reserved.

This paper introduces two uncertain continuous portfolio selection models under the assumption that securities follow uncertain differential equations. The models are established to be consistent with the goals of investors based on expected value criterion. Solution methods for the models are proposed based on the α-pathes of uncertain differential equation and genetic algorithm. An example is...

It has been proved that uncertain differential equation (UDE) has a unique solution, under the conditions that the coefficients are global Lipschitz continuous. This paper extends this existence and uniqueness theorem from the following aspect: UDE has a unique solution, under the conditions that the coefficients are local Lipschitz continuous. Besides, it is also proved that UDE has at least o...

In this paper I show that a kind of infinite-order predicate logic can be regarded as non-Archimedean or p-adic valued. I have considered two principal versions of non-Archimedean valued predicate logical calculi: p-adic valued extension of BL∀ and hyper-valued extension of à LΠ∀. These logical systems are considered for the first time. c ©2010 World Academic Press, UK. All rights reserved.

One of the famous mathematical inequalities is Minkowski’s inequality. It is an important inequality from both mathematical and application points of view. In this paper, a Minkowski type inequality for fuzzy integrals is studied. The established results are based on the classical Minkowski inequality for integrals. Moreover, a generalized Minkowski type inequality for fuzzy integrals is sugges...

Conventional Fuzzy regression using possibilistic concepts allows the identification of models from uncertain data sets. However, some limitations still exist. This paper deals with a revisited approach for possibilistic fuzzy regression methods. Indeed, a new modified fuzzy linear model form is introduced where the identified model output can envelop all the observed data and ensure a total in...
