On the uniform stability of recovering sine-type functions with asymptotically separated zeros

Sergey Buterin

We obtain a uniform stability of recovering entire functions of a special form from their zeros. To this form, one can reduce the characteristic determinants of strongly regular di…

Sturm-Liouville-type operators with frozen argument and Chebyshev polynomials

Tzong-Mo Tsai, Hsiao-Fan Liu, Sergey Buterin +2

The paper deals with Sturm-Liouville-type operators with frozen argument of the form $ℓ y := - y^{''} (x) + q (x) y (a),$ $y^{(α)} (0) = y^{(β)} (1) = 0,$ where $α, β \in {0, 1}$ and $a \in [0, 1]$ is…
