Weights with both absolutely continuous and discrete components: Asymptotics via the Riemann-Hilbert approach
Xiao-Bo Wu, Yu Lin, Shuai-Xia Xu +1
We study the uniform asymptotics for the orthogonal polynomials with respect to weights composed of both absolutely continuous measure and discrete measure, by taking a special cla…
Painlevé III asymptotics of Hankel determinants for a perturbed Jacobi weight
Zhao-Yun Zeng, Shuai-Xia Xu, Yu-Qiu Zhao
We study the Hankel determinants associated with the weight where , , , is analytic in a domain containin…
Uniform asymptotics for discrete orthogonal polynomials on infinite nodes with an accumulation point
Xiao-Bo Wu, Yu Lin, Shuai-Xia Xu +1
In this paper, we develop the Riemann-Hilbert method to study the asymptotics of discrete orthogonal polynomials on infinite nodes with an accumulation point. To illustrate our met…
Location of Poles for the Hastings-McLeod Solution to the Second Painlevé Equation
Min Huang, Shuai-Xia Xu, Lun Zhang
We show that the well-known Hastings-McLeod solution to the second Painlevé equation is pole-free in the region $\arg x \in [-\fracπ{3},\fracπ{3}]\cup [\frac{2π}{3},\frac{ 4 π}{3}]…
Painlevé III asymptotics of Hankel determinants for a singularly perturbed Laguerre weight
Shuai-Xia Xu, Dan Dai, Yu-Qiu Zhao
In this paper, we consider the Hankel determinants associated with the singularly perturbed Laguerre weight , , and . When the matr…
Critical edge behavior in the modified Jacobi ensemble and Painlevé equations
Shuai-Xia Xu, Yu-Qiu Zhao
We study the Jacobi unitary ensemble perturbed by an algebraic singularity at . For fixed , this is the modified Jacobi ensemble studied by Kuijlaars {\it{et al.}} The main…
