It would be helpful to include some words describing the use of $i^*, \pi^*$ to denote induced maps on homology. This isn't entirely clear from context. — Preceding unsigned comment added by Dzackgarza (talk • contribs) 03:30, 9 December 2019 (UTC)
This says that the Leray-Hirsch theorem is a special case of the Leray spectral sequence. This could use some explanation. The connection between sheaf cohomology and singular cohomology is subtle, and they don't always agree with each other. — Preceding unsigned comment added by 2600:1702:E30:7870:2C8A:9CCF:87DB:F705 (talk) 00:26, 29 April 2020 (UTC)
