On Generalized von Neumann Inverse Graphs of Finite Commutative Regular Rings
Felicia Servina Djuang, Indah Emilia Wijayanti, Yeni Susanti
Let be a ring with identity. The generalized von Neumann inverse graph of , denoted by , is defined as the graph whose vertex set is , where two distinc…
Shuriken Graphs Arising from Clean Graphs of Rings and Their Properties Relative to Base Graphs
Felicia Servina Djuang, Indah Emilia Wijayanti, Yeni Susanti
Let be a finite ring with identity. The idempotent graph is the graph whose vertex set consists of the non-trivial idempotent elements of , where two distinct vertice…
Isomorphism of Clean Graphs over and Structural Insight into
Felicia Servina Djuang, Indah Emilia Wijayanti, Yeni Susanti

On -derivations and Jordan -derivations on modules
Gusti Ayu Dwi Yanti, Indah Emilia Wijayanti
Let be a ring with identity, right modules over . An additive mapping from to is called derivation on ring if it satisfies the Leibniz condition. If $…
Clean Graphs and Idempotent Graphs over Finite Rings: An Approach Based on Z_n
Felicia Servina Djuang, Indah Emilia Wijayanti, Yeni Susanti
Let be a finite ring with identity. The idempotent graph is the graph whose vertex set consists of the non-trivial idempotent elements of , where two distinct vertice…
On Codes over Eisenstein Integers
Abdul Hadi, Uha Isnaini, Indah Emilia Wijayanti +1
We propose constructions of codes over quotient rings of Eisenstein integers equipped with the Euclidean, square Euclidean, and hexagonal distances as a generalization of codes ove…
