REPDIGITS AS DIFFERENCE OF TWO PELL OR PELL-LUCAS NUMBERS

Erduvan, Fatih; Keskin, Refik (2023)

Abstract: Bismuth vanadate (BiVO4)-cement composites were coated on concrete surfaces, which were fabricated with differing amounts of BiVO4 (0, 20, and 40 wt%) in Portland cement. The photocatalytic methylene blue (MB) ...
Repdigits basebas products of two Lucas numbers

Erduvan, Fatih; Keskin, Refik; Siar, Zafer (NATL INQUIRY SERVICES CENTRE PTY LTD, )

Let (L-n) be the sequence of Lucas numbers defined byL(0)= 2, L-1= 1, andL(n)=Ln-1+L(n-2)forn >= 2. Let 0 <= m <= nandb= 2,3,4,5,6,7,8,9.In this study, we show that ifL(m)L(n)is a repdigit in the baseband has at least two ...
