Standard model of particle physics for mathematicians
These are not good books to learn from. I find these two to be to long and drawn out. They lack focus. They are missing and overall arc or plot and feel more like an amalgam of thousands of snippets written by different people with little regard to what the others were writing. These books may contain everything, but they also contain everything. On the plus side, I enjoy the historical annotations and stories. |

This is similar to this question at the Physics Exchange: theoreticalphysics.stackexchange.com/questions/222/… |

Is an A-infinity thing the same the same as strict thing viewed through a homotpy equivalence?
@Clark: I think that is indeed what I am asking. I am thinking of A_\infty as up-to-coherent-homotopy monoid/group/algebra/..., but I am trying to get a better feel of what exactly that means. It would be nice to be able to think that this was a strict (up-to-identity) monoid/... smudged by a homotopy equivalence. My question thus has two parts: (1) if I have a strict structure and smudge it through a homotopy equivalence, do I get an A_\infty structure? (2) If I have an A_\infty structure, can I assume it arose in this way? |
