I was born in 1965 and I live near Torino, in Italy. I'm happily married with my lovely wife Nadia and we have three wonderful sons, Antida, Gioele and Tiziano. I have always been interested in math topics and above all in Number Theory. In this field I was able to develop some original results that concern primality criteria for pairs of prime numbers. These were posted to the NMBRTHRY Mailing List and also to primenumbers@yahoogroups.com.
