Problem 1
Use the precise definitions, state all hypotheses, apply research question, and verify the conclusion against a boundary case or independent theorem.
Faculty solution guide
Accept equivalent mathematically correct reasoning. Require explicit definitions, theorem hypotheses, proof structure, verification, and limitations.
Use the precise definitions, state all hypotheses, apply research question, and verify the conclusion against a boundary case or independent theorem.
Identify the first invalid inference, missing hypothesis, quantifier error, unjustified limit interchange, or unproved existence claim; then supply a valid repair.
A complete response explicitly states the definitions, domain, hypotheses, exact target, and theorem dependencies for Selecting a Feasible Theorem-Level Question.
The argument must address narrowing a topic to a precise and defensible claim with each nontrivial step justified and the final conclusion restated.
A strong application explains the mathematical model in advanced coursework, independent study, undergraduate research, graduate preparation, and mathematical publication, verifies conditions, and names at least one limitation.
Accept a second valid proof, a counterexample showing necessity of a hypothesis, an independent estimate, or a reproducible finite check that is correctly described as supporting evidence.
