A Note on Affine Invariant Cost Functions

Jingbo Liu

We show that any affine invariant function on the set of positive definite matrices must factor through the determinant function, as long as the restriction of the function to scal…

On the value distribution of the Riemann zeta-function and the Euler gamma-function

Qi Han, Jingbo Liu, Qiong Wang

We prove some uniqueness results for the Riemann zeta-function and the Euler gamma-function by virtue of shared values using the value distribution theory.

On differential independence of $\mathboldζ$ and $\mathboldΓ$

Qi Han, Jingbo Liu

In this note, we will prove that $\mathboldζ$ and $\mathboldΓ$ can not satisfy any differential equation generated through a family of functions continuous in $\mathboldζ$ with pol…

Algebraic differential independence regarding the Riemann -function and the Euler -function

Qi Han, Jingbo Liu

In this paper, we prove that cannot be a solution to any nontrivial algebraic differential equation whose coefficients are polynomials in $\boldsymbolΓ,\boldsymbolΓ^…

Universal sums of -gonal numbers

Ben Kane, Jingbo Liu

In this paper we study universal quadratic polynomials which arise as sums of polygonal numbers. Specifically, we determine an asymptotic upper bound (as a function of ) on the…

On a Waring's problem for integral quadratic and hermitian forms

Constantin N. Beli, Wai Kiu Chan, Maria Ines Icaza +1

For each positive integer , let be the smallest integer such that if an integral quadratic form in variables can be written as a sum of squares of integra…
