**Computational Algebraic Topology**

**Announcements**

The fourth problem sheet, which covers material from the second part of the course, is now available. The third problem sheet is due on Monday the 4th of March.

Want more Persistent Homology in your life? Here are the papers I mentioned recently which describe the existence and computation of barcodes as well as a readable account of the stability theorem for persistence modules.

The second problem set was collected on Monday of Week 5. The first problem set, which was not collected, is still available here.

**Notes**

You may (and should!) use the following lecture notes as an outline for reviewing the material. See also Prof Tillmann's webpage for some useful resources.

Lec 01: Complexes (Prof Tillmann's slides)

Lec 02: Homology (minor fixes on 30/1)

Lec 03: Functoriality (major fixes on 30/1)

Lec 04: Cohomology

Lec 05: Persistence (Stability Theorem added on 7/2)

Lec 06: Cellular Sheaves

Lec 07: Discrete Morse Theory (HUGE update 14/2. Happy Valentine's Day.)

Here are Professor Abramsky's lecture slides (to be used in Weeks 5-8)

Lec 08: Quantum computation

Lec 09: The topology of paradox

Lec 10: Quantum realizability

Lec 11: Sheaf cohomology, quantum non-locality and contextuality 1

Lec 12: Sheaf cohomology, quantum non-locality and contextuality 2

Lec 13: Sheaf cohomology, quantum non-locality and contextuality 3

The following research papers serve as references for the material covered in the second half of this course:
