Named-entity recognition
gpt-5-mini
Instruction
Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).
Input
Phrase: Fredholm determinant | Statement: [Ivar Fredholm, hasConceptNamedAfter, Fredholm determinant]

-
A.
Selberg integral
The Selberg integral is a fundamental multidimensional generalization of Euler’s beta integral that plays a central role in random matrix theory, combinatorics, and special functions.
-
B.
Fredholm operator
A Fredholm operator is a bounded linear operator between Banach (or Hilbert) spaces with finite-dimensional kernel and cokernel and a closed range, characterized by its integer-valued index.
-
C.
Fredholm alternative
The Fredholm alternative is a fundamental result in functional analysis that characterizes when linear equations involving compact or Fredholm operators have unique solutions, infinitely many solutions, or no solution, in terms of the associated homogeneous problem.
-
D.
Fisher–Hartwig conjecture
The Fisher–Hartwig conjecture is a result in mathematical analysis that predicts the asymptotic behavior of Toeplitz determinants with singular symbols, extending the classical Szegő limit theorem.
-
E.
Borg–Marchenko theorem
The Borg–Marchenko theorem is a fundamental result in inverse spectral theory that characterizes when a potential in a one-dimensional Schrödinger operator is uniquely determined by its spectral data.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
