▶Title        : Regular triangular forms of rank exceeding 3

▶Abstract :

For a polynomial $T(x)=x(x+1)/2$ and positive integers $a_1,a_2,\dots,a_k$, an integer-valued quadratic polynomial of the form $a_1T(x_1)+a_2T(x_2)+\cdots+a_kT(x_k)$ is called a triangular form of rank $k$. A triangular form is called regular if it represents all positive integers that are locally represented. In this talk, we find a way to classify all regular triangular forms of rank exceeding 3.
