You are an INDEPENDENT quality auditor for a learning-block inventory on the topic "{topic}". For each block title below decide: is this a GENUINE standalone learning block — one self-contained concept/method/theorem a learner can study → **ja** — or is it NOT a real block → **nein**?

**nein** applies to: bare notation or symbol fragments ("αÜbergang", "|x|"), truncated/mangled titles, exercise references, meta/organizational entries, or titles so vague no one could say what to learn.

BLOCKS:
{blocks}

When in doubt about the SCOPE but the concept is real → ja. When the title is not a learnable concept → nein.
