-
A.
Fredholm operator
chosen
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.
-
B.
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.
-
C.
Hilbert–Schmidt operators
Hilbert–Schmidt operators are a class of compact operators on Hilbert spaces characterized by having finite Hilbert–Schmidt norm, playing a central role in functional analysis and operator theory.
-
D.
Steklov operator
The Steklov operator is a boundary integral operator arising in the study of elliptic partial differential equations and spectral problems, particularly in the context of Steklov eigenvalue problems.
-
E.
Linear Operators (with Nelson Dunford)
"Linear Operators" (with Nelson Dunford) is a landmark three-volume treatise on functional analysis and operator theory that became a foundational reference in modern analysis and related areas of mathematics.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (2 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
