Abstract of talk
The set of full matrices (i.e., matrices whose elements are relatively prime) of the second order over an adequate ring 
is investigated. The concept of an adequate element in non-commutative rings is introduced. It is proved that nonsingular full second order matrices are right (left) adequate elements in the ring of second order matrices over .
