# Almost universal ternary sums of polygonal numbers

Almost universal ternary sums of polygonal numbers For a natural number m, generalized m-gonal numbers are those numbers of the form $$p_m(x)=\frac{(m-2)x^2-(m-4)x}{2}$$ p m ( x ) = ( m - 2 ) x 2 - ( m - 4 ) x 2 with $$x\in \mathbb Z$$ x ∈ Z . In this paper we establish conditions on m for which the ternary sum $$p_m(x)+p_m(y)+p_m(z)$$ p m ( x ) + p m ( y ) + p m ( z ) is almost universal. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research in Number Theory Springer Journals

### Abstract

For a natural number m, generalized m-gonal numbers are those numbers of the form $$p_m(x)=\frac{(m-2)x^2-(m-4)x}{2}$$ p m ( x ) = ( m - 2 ) x 2 - ( m - 4 ) x 2 with $$x\in \mathbb Z$$ x ∈ Z . In this paper we establish conditions on m for which the ternary sum $$p_m(x)+p_m(y)+p_m(z)$$ p m ( x ) + p m ( y ) + p m ( z ) is almost universal.
