In differential topology, Morse theory enables one to analyze the topology of a manifold by studying differentiable functions on that manifold.

What does it mean that homotopy is generic?

"Generic" usually refers to open and dense. Assume $M$ is a closed smooth manifold. Let $$C^\infty(M)$$ be the space of all smooth real valued functions. Topologize this with respect to the Whitney …

How does the Framed Function Theorem simplify Cerf Theory?

The framed function theorem tells you that up to "contractible choice" a compact manifold admits a framed function: i.e., a function as you prescribe. Furthermore, a framed function is supposed to giv …

Constructing ($\infty, 1)$-category from Morse theory on a manifold

This problem has a long history going back at least to the paper of Cohen, Jones and Segal (available here: http://www.kurims.kyoto-u.ac.jp/~kyodo/kokyuroku/contents/pdf/0883-04.pdf). In terms of your …

My recollection is that Milnor's proof gives exactly what you are asking. In fact, see the remark on the bottom of page 17 of his book.

Stratification of smooth maps from R^n to R?

It looks to me that what you are really interested in is the Thom-Boardman stratification of the function space. For that I would recommend the well-written, Stable Mappings and Their Singularities b …

Unstable manifolds of a Morse function give a CW complex

(1). Some experts tell me that Laudenbach's paper is incomplete and contains gaps. I will retract this for now. I do recall being told this, but I am not aware at this point in time where the gaps …
