### Prerequisite

MAT 530 or its contents (basic topology, fundamental group and covering spaces)

### Textbook

 Textbook: Homology of Cell Complexes Notes on the course of  Norman Steenrod by George E. Cooke and Ross L. Finney Princeton University Press; 1st edition (1967) We like this treatment because it straddles the zone between geometry and algebra and provides a solid basis for understanding algebraic topology.

### Topics

The sequence of concepts goes as follows:
1.  An elegant and clear definition of  cell complex
2. The distinction between regular cell complexes and general cell complexes (the CW complexes of J.H.C. Whitehead)
3. Homology groups of regular cell complexes
4. The invariance theorem depending on the functorial aspects of regular cell complex homology
5. Singular homology (in the more geometric variant of Steenrod)
6. Introductory homotopy theory
7. Skeletal homology for general cell complexes.

### Disability Support Services

If you have a physical, psychological, medical, or learning disability that may impact your course work, please contact Disability Support Services (631) 632-6748 or http://studentaffairs.stonybrook.edu/dss/. They will determine with you what accommodations are necessary and appropriate. All information and documentation is confidential. Students who require assistance during emergency evacuation are encouraged to discuss their needs with their professors and Disability Support Services. For procedures and information go to the following website: http://www.sunysb.edu/facilities/ehs/fire/disabilities.

### Academic Integrity

Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Faculty are required to report any suspected instance of academic dishonesty to the Academic Judiciary. For more comprehensive information on academic integrity, including categories of academic dishonesty, please refer to the academic judiciary website at http://www.stonybrook.edu/uaa/academicjudiciary/. Critical Incident Management Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of Judicial Affairs any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, and/or inhibits students' ability to learn.
