eCHT: online algebraic topology course using Hatcher’s textbook

Hi all,

In Winter 2023, the electronic Computational Homotopy Theory (eCHT) online research community is offering an online algebraic topology course using Hatcher’s textbook. More information is available at the link:

Please see the below information from Dan Isaksen:

I’m writing about an online course to be offered in Winter 2023 that may be a good fit for people in applied topology. Please share this information with anyone who might be interested.

The electronic Computational Homotopy Theory (eCHT) research community is an online home for mathematicians with interests in homotopy theory and related topics. The community is sponsored by a National Science Foundation (NSF) Research Training Group (RTG) grant. See
for more information about eCHT in general.

In Winter 2023, we will offer an online graduate course on introductory algebraic topology. This course could be well-suited to some students, especially if their institutions are not offering introductory algebraic topology this year. Our target audience includes first-year PhD students with interests in algebra, geometry, or topology; and masters students who are preparing to enter a PhD program soon. We are also open to enrolling advanced undergraduate students under certain circumstances.

for more information, including a syllabus, grading policies, prerequisites, and application instructions. We do not charge tuition, but students are generally expected to enroll for independent study credits at their home institutions.

Please reach out if you have any questions.
