In this paper, we prove a conjecture posed by Li-Yang in cite{ly3}. We prove the following result: Let $f(z)$ be a nonconstant entire function, and let $a(z) otequivinfty, b(z) otequivinfty$ be two distinct small meromorphic functions of $f(z)$. If $f(z)$ and $f^{(k)}(z)$ share $a(z)$ and $b(z)$ IM. Then $f(z)equiv f^{(k)}(z)$, which confirms a conjecture due to Li and Yang (in Illinois J. Math. 44:349-362, 2000).
In this article, we obtain a strict inequality between the conjugate Hardy $H^{2}$ kernels and the Bergman kernels on planar regular regions with $n>1$ boundary components, which is a conjecture of Saitoh.
A typical decomposition question asks whether the edges of some graph $G$ can be partitioned into disjoint copies of another graph $H$. One of the oldest and best known conjectures in this area, posed by Ringel in 1963, concerns the decomposition of
We prove that if the set of unordered pairs of real numbers is colored by finitely many colors, there is a set of reals homeomorphic to the rationals whose pairs have at most two colors. Our proof uses large cardinals and it verifies a conjecture of
We prove a conjecture of Ohba which says that every graph $G$ on at most $2chi(G)+1$ vertices satisfies $chi_ell(G)=chi(G)$.
We present a proof of the compositional shuffle conjecture, which generalizes the famous shuffle conjecture for the character of the diagonal coinvariant algebra. We first formulate the combinatorial side of the conjecture in terms of certain operato
