On the Diophantine Equations Arising from Three-Term -Concatenations in Pell-Type Sequences
Kouèssi Norbert Adédji, Marija Bliznac Trebješanin, Jelena Pleština
We study the Diophantine problem of representing a Pell or Pell--Lucas number as the base- concatenation of three other Pell or Pell--Lucas numbers. Under the condition that the…

Sums of three Fibonacci numbers as concatenations of three repdigits in base
Passimzouwé Dagou, Pagdame Tiebekabe, Kouèssi Norbert Adédji +1
In this paper, we investigate sums of three Fibonacci numbers that can be expressed as concatenations of three repdigits in base , where is an integer. We prove that fo…

Thabit and Williams Numbers Base as a Sum or Difference of Two -Repdigits
Kouèssi Norbert Adédji, Marija Bliznac Trebješanin, Jelena Pleština
We investigate cases where Thabit and Williams numbers in base can be expressed as the sum or difference of two -repdigits. For specific values of and , we describe p…
