Universal mixed sums of generalized $4$ - and $8$ -gonal numbers

Jangwon Ju, Byeong-Kweon Oh

An integer of the form $P_{m} (x) = \frac{( m - 2 ) x ^{2} - ( m - 4 ) x}{2}$ for an integer $x$ , is called a generalized $m$ -gonal number. For positive integers $α_{1}, \dots, α_{u}$ and $β_{1}, \dots, β_{v}$ ,…

Universal sums of generalized pentagonal numbers

Jangwon Ju

For an integer $x$ , an integer of the form $P_{5} (x) = \frac{3 x ^{2} - x}{2}$ is called a generalized pentagonal number. For positive integers $α_{1}, \dots, α_{k}$ , a sum $Φ_{α_1,\dots,α_k}(x_1,x_…
