Manin's conjecture for singular cubic hypersurfaces

Jianya Liu, Tingting Wen, Jie Wu

Let S Q denote x 3 = Q(y 1 ,. .. , y m)z where Q is a primitive positive definite quadratic form in m variables with integer coefficients. This S Q ranges over a class of singular…

On forms in prime variables

Jianya Liu, Lilu Zhao

Let $F_{1}, \dots, F_{R}$ be homogeneous polynomials of degree $d \geq 2$ with integer coefficients in $n$ variables, and let $F = (F_{1}, \dots, F_{R})$ . Suppose that $F_{1}, \dots, F_{R}$ …

Representation by sums of unlike powers

Jianya Liu, Lilu Zhao

It is proved that all sufficiently large integers $n$ can be represented as $n = x_{1}^{2} + x_{2}^{3} + \dots + x_{13}^{14},$ where $x_{1}, \dots, x_{13}$ are positive integers. This improves upo…

Subsampling Bias and The Best-Discrepancy Systematic Cross Validation

Liang Guo, Jianya Liu, Ruodan Lu

Statistical machine learning models should be evaluated and validated before putting to work. Conventional k-fold Monte Carlo Cross-Validation (MCCV) procedure uses a pseudo-random…

Gaussian primes in almost all narrow sectors

Bingrong Huang, Jianya Liu, Zeév Rudnick

We study Gaussian primes lying in narrow sectors, and show that almost all such sectors contain the expected number of primes, if the sectors are not too narrow.

On a senary quartic form

Jianya Liu, Jie Wu, Yongqiang Zhao

We count rational points of bounded height on the non-normal senary quartic hypersurface x 4 = (y 2 1 + $\times$ $\times$ $\times$ + y 2 4)z 2 in the spirit of Manin's conjecture.
