Abstract

Let $ϕ$ be a fixed polynomial with integer coefficients, positive leading coefficient and degree $k\geq2$. We prove that the values $2ϕ(n)$, $1\leq n\leq N$, can be written as the sum of two primes, apart from at most $N^{α_k+o(1)}$ exceptional indices, where $α_k<1$. For quadratic polynomials the exponent is $1/2$, for cubic polynomials $5/8$, for quartic polynomials $3/4$, and for $k>4$ it is $1-1/(k+1)$. The proof combines a fourth-moment estimate over primes with mean-value estimates over arbitrary subsets of polynomial sequences.

Qin's Algorithm, Continued Fractions and 2-dimensional Lattices

In his ``Mathematical Treatise in Nine Sections''(1247), Jiushao Qin introduced ``the Dayan method of deriving unity'' for computing modular inverses, an essential component of his treatment of the Chinese remainder theorem. A distinctive feature of Qin's algorithm is its use of a state consisting of four nonnegative integers arranged in a matrix. In this paper, we investigate the mathematical structure of these states and their connections with continued fractions and two-dimensional lattices. By introducing a signed version of the state, we obtain a natural matrix representation that reveals the convergents of continued fractions and gives direct derivations of several classical results. We then show that the signed states form bases of a family of two-dimensional lattices arising from modular congruences. In particular, we prove that a shortest lattice vector can be obtained from the rows of a signed state or their sum or difference. We also study the monotonicity of the inner products of the state vectors and discuss a subsequent result that locates a shortest vector in one of two consecutive states. It is surprising that a shortest lattice vector is found in a highly structure sequence of states. These results demonstrate that the state structure of Qin's algorithm provides a unified framework for understanding modular inversion, continued fractions, and shortest vectors in two-dimensional lattices.

The symmetrized sum of finite $q$-multiple harmonic sums with one exceptional index

In this paper, we give explicit expressions for $q$-harmonic sums on $1-\cdots-1,A,1-\cdots-1$ indices. The case $A=1$ has been extensively studied, and a variety of identities, explicit evaluations, and structural properties are known. Likewise, numerous explicit evaluations are available for $q$-multiple zeta values and $q$-harmonic sums with uniform indices $A-\cdots-A$. Although several methods are available for treating non-uniform indices, explicit evaluations for the pattern $1-\cdots-1,A,1-\cdots-1$ remain comparatively scarce. The case $A=2$ was settled only recently. In this paper, we extend this framework to the general case $A\ge3$ as the total sum with the theory of the elementary symmetric functions, though we do not generally evaluate each summand at a prescribed position of $A$. We obtain explicit formulas in terms of binomial coefficients and degenerate Bernoulli numbers. Some expressions about $2-\cdots-2,A,2-\cdots-2$ are also shown.
