Abstract
In contrast to scalar Riemann–Hilbert problems, a general matrix Riemann–Hilbert problem cannot be solved in terms of Sokhotskyi–Plemelj integrals. As far as the authors know, the exact solutions are known for a class of homogeneous matrix Riemann–Hilbert problems with commutative and factorable kernels. This article considered matrix Riemann–Hilbert problems in which all the partial indices are zero and the logarithms of the components of the kernels and their non-homogeneous vectors are exponential-type (equivalently, band-limited) functions. Then, it develops exact solutions for such matrix Riemann–Hilbert problems. Applications in a class of spectral factorizations and a class of the Wiener–Hopf system of integrations are given.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
