The Landau's problems. I-II
This is a work in two parts devoted to solutions of the so-called {\em four Landau's problems} in Number Theory, listed by Edmund Landau at the 1912 International Congress of Mathematics. In Part I the {\em Goldbach's conjecture} is proved. (This is the first Landau's problems.) In Part II the other three Landau's problems are considered and solved too.
