A curious result related to Kempner's series

Bakir Farhi

It is well known since A. J. Kempner's work that the series of the reciprocals of the positive integers whose the decimal representation does not contain any digit 9, is convergent…

Nontrivial lower bounds for the least common multiple of some finite sequences of integers

Bakir Farhi

We present here a method which allows to derive a nontrivial lower bounds for the least common multiple of some finite sequences of integers. We obtain efficient lower bounds (whic…
