An Injective Pseudo-BCI Algebra is Trivial

Discussiones Mathematicae - General Algebra and Applications, 2019

Neutrosophic Quadruple BCK/BCI-Algebras [PDF]

Axioms, 2018
The notion of a neutrosophic quadruple BCK/BCI-number is considered, and a neutrosophic quadruple BCK/BCI-algebra, which consists of neutrosophic quadruple BCK/BCI-numbers, is constructed. Several properties are investigated, and a (positive implicative)

A Novel Study Based on Fuzzy p-Ideals of BCI-Algebras

Journal of Function Spaces, 2023
In this paper, we propose the concept of ∈,∈∨j∗,qj-fuzzy p-ideals in “BCI-algebras.” We show that “∈,∈∨q-fuzzy p-ideals” and “∈∨j∗,qj,∈∨j∗,qj-fuzzy p-ideals” are “∈,∈∨j∗,qj-fuzzy p-ideals.” However, the converse is not true, then presented examples.

P-CLOSURE IN PSEUDO BCI-ALGEBRAS [PDF]

Journal of Algebraic Systems, 2020
In this paper, for any non-empty subset C of a pseudo BCI-algebra X, the concept of p-closure of C, denoted by C(pc), is introduced and some related properties are investigated.

Graphs Based on BCK/BCI-Algebras [PDF]

International Journal of Mathematics and Mathematical Sciences, 2011
The associated graphs of BCK/BCI-algebras will be studied. To do so, the notions of (l-prime) quasi-ideals and zero divisors are first introduced and related properties are investigated. The concept of associative graph of a BCK/BCI-algebra is introduced,

Interior BCK/BCI-Algebras [PDF]

International Journal of Computational Intelligence Systems, 2021
The notions of interior BCK/BCI-algebras, positive implicative interior BCK-algebras, (weak) interior ideals, positive implicative interior ideals, a positive implicative weak interior ideal of type 1, type 2, and type 3 are introduced, and related properties are investigated. A mapping is provided to the set of all involutions of a bounded BCK-algebra

Doubt fuzzy BCI‐algebras [PDF]

International Journal of Mathematics and Mathematical Sciences, 2002
The aim of this note is to introduce the notion of doubt fuzzy p‐ideals in BCI‐algebras and to study their properties. We also solve the problem of classifying doubt fuzzy p‐ideals and study fuzzy relations on BCI‐algebras.

Generalization of Fuzzy Soft BCK/BCI-Algebras

Journal of Mathematics, 2021
In this paper, the notions of ∈,∈∨q-fuzzy soft BCK/BCI-algebras and ∈,∈∨q-fuzzy soft sub-BCK/BCI-algebras are introduced, and related properties are investigated.

Seasonality of reproduction in an ever‐wet lowland tropical forest in Amazonian Ecuador

Ecology, Volume 104, Issue 9, September 2023., 2023
Abstract Flowering and fruiting phenology have been infrequently studied in the ever‐wet hyperdiverse lowland forests of northwestern equatorial Amazonía. These Neotropical forests are typically called aseasonal with reference to climate because they are ever‐wet, and it is often assumed they are also aseasonal with respect to phenology.
