Konyagin, Sergei V.; Luca, Florian; Stănică, Pantelimon (2009);In this note, we prove an estimate on the count of Fibonacci numbers whose sum of divisors in also a Fibonacci number. As a corollary, we find that the series of reciprocals in indices of such Fibonacci numbers is convergent.
Ang, Kwee Hua (Monterey, California. Naval Postgraduate School, 1995-03);The Binary Decision Diagram (BDD) is a very useful representation in the design and verification of switching functions. This is due to to its compactness, where size is measured by the number of nodes. In the implementation ...
Luca, Florian; Stănică, Pantelimon (2013);Here, we look at the Fibonacci and Lucas numbers whose Euler function is a factorial, as well as Lucas numbers whose Euler function is a product of power of two and power of three
