Are wedge products defined the same in various areas of mathematics? For instance the wedge product in Geometric Algebra (Clifford, etc) and the wedge product...
Herb, As far as I know, it has the same definition - more or less the completely anti-symmetric tensor product. Every text I've read - from GA, to differential...
I believe wedge products (or exterior products) refer to the same thing in each case but the definitions sound different depending on whether they are looking...
Most of the members here seem to have a good a grasp of mathematics at an advanced level, so "The Shape of Space" by Jeffrey R. Weeks may not be of direct...

Today, I finally got clear on the basic difference and relationship between Configuration Space and Phase Space. Configuration Space is the space of all...
I'll just jump in and add the a Phase Space is a familiar concept to engineers, since it applies to all possible states of classical systems, like mechanical...

By the time you finish RTR you realize that Penrose is generally negative towards String Theory, at least as a total and final theory of Reality. While Penrose...
Doesn't the configuration space just refer to the possible *positions* and the phase space the possible positions *and momenta*? In other words, the phase...
... From what I understand this is correct (as long as we generalize the latter phase space in other contexts to include observables other than just momentum...
