Suppose $$\{P_{n}^{(\alpha , \beta )}(x)\} _{n=0}^\infty $$ is a sequence of Jacobi polynomials with \alpha >-1.$$ We discuss special cases question raised by Alan Sokal at OPSFA in 2019, namely, whether the zeros P_{n}^{(\alpha ,\beta )}(x)$$ and P_{n+k}^{(\alpha + t, s are interlacing if $$s,t >0$$ k \in {\mathbb {N}}.$$ consider two this for consecutive degree prove that P_{n+1}^{(\alpha 1 )...
