Losely speaking, a topological twist has the effect that it exchanges some of the worldsheet supersymmetry with topological symmetry, which can be much easier investigated. Building a BRST charge from these symmetries, we find in the two-dimensional case that in its cohomology are either Kähler...
I have further evidence that the action gives access to the non-perturbative regime of M-theory: The finite non-perturbative regime of the membrane field action is equal to (2,0) 6d superconformal field theory on M cross C, where M is a four-manifold and C is a, possibly punctured, complex...
What I can extract from the topological version of M-theory is that its physical cousin should be described by some sigma-model on a 2-brane, that degenerates into the five superstring theories if we play with its parameters. To put it in a similar geometric picture as for the topological...
Thanks for the explanation. However, the membranes I talk about are one-parameter families of strings. In this sense the membrane field relates different string fields on different backgrounds with each other. They do this because they describe paths on the boundary of superconformal field...
Thanks for your answer,
I think I did read this before and some of it is familiar from the point of view I see the subject. However, I was able to construct the before mentioned membrane field theory and showed that it has the above mentioned properties and that it reduces to Seidberg-Witten...
Hey guys, I just wanted to know if you think that a membrane field theory could ellucidate the non-perturbative framework of M-theory?
Let me specify and explain what I mean by that: String field theory was intoduced to study the non-perturbative regime of string theory and some achievements in...
