Problem 1
Begin from the exact definitions, verify all hypotheses, use K finite simplicial complex, distinguish local from global conclusions, and test the result on a standard model and a boundary or counterexample case.

Simplicial Complexes and Triangulated Spaces
Accept equivalent mathematically correct reasoning. Require explicit definitions, theorem hypotheses, proof structure, verification, and limitations.
Problem 2
Identify the first invalid inference, missing hypothesis, quantifier error, unjustified limit interchange, or unproved existence claim; then supply a valid repair.
Problem 3
A complete response explicitly states the definitions, domain, hypotheses, exact target, and theorem dependencies for Simplicial Complexes and Triangulated Spaces.
Problem 4
The argument must address encoding spaces combinatorially with vertices, edges, faces, and higher simplices with each nontrivial step justified and the final conclusion restated.
Problem 5
A strong application explains the mathematical model in topological data analysis, image shape, mesh processing, sensor networks, and manifold invariants, verifies conditions, and names at least one limitation.
Problem 6
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.
