Thin Bases of Order Two Original Research Article

A set Asubset of or equal toimage0 is called a basis of order two if A+Acolon, equals{a+a′ mid a, a′set membership, variantA}=image0. If nset membership, variantimage then A(n) denotes the number of aset membership, variantA with 1less-than-or-equals, slantaless-than-or-equals, slantn. In this paper bases A, B, C of order two are given such thatimage
