comment Teaching myself differential topology and differential geometry
@JavierÁlvarez Sorry to bother you on this old post but the highest math class I have taken thus far is linear algebra. Would the list you recommend help me or should I start reading more basics books? I am going to take abstract algebra, complex analysis, and analysis 1 next semester.
