Direct Sums of Strongly Lifting Modules

Shahabaddin Ebrahimi Atani, Mehdi Khoramdel and Saboura Dolati Pishhesari

Kyungpook Mathematical Journal 2020; 60: 673-682

For the recently defined notion of strongly lifting modules, it has been shown that a direct sum is not, in general, strongly lifting. In this paper we investigate the question: When are the direct sums of strongly lifting modules, also strongly lift...
Key Words:

lifting modules, strongly lifting modules, coclosed submodules, hollow modules, relatively strongly projective modules

On n-Amitsur Rings

Baatar Ochirbat, Deolinda I. C. Mendes ,Sodnomkhorloo Tumurbat

Kyungpook Mathematical Journal 2020; 60: 711-721

The concepts of an Amitsur ring and a hereditary Amitsur ring, which were introduced and studied by S. Tumurbat in a recent paper, are generalized. For a positive integer n, a ring A is said to be an n-Amitsur ring if

The p-deformed Generalized Humbert Polynomials and Their Properties

Rajesh V. Savalia, B. I. Dave

Kyungpook Mathematical Journal 2020; 60: 731-752

We introduce the p-deformation of generalized Humbert polynomials. For these polynomials, we derive the differential equation, generating function relations, Fibonacci-type representations, and recurrence relations and state the companion matr...

The Multi-step Adomian Decomposition Method for Approximating a Fractional Smoking Habit Model

Mohammad Zuriqat, Asad Freihat

Kyungpook Mathematical Journal 2020; 60: 753-765

Smoking is one of the main causes of health problems and continues to be one of the world’s most significant health challenges. In this paper, we use the multi-step Adomian decomposition method (MSADM) to obtain approximate analytical solutions for...
