Description
In a recent work of Gaiotto,Moore and Witten the
``algebra of the infrared" for certain massive 2d theories with (2,2)
supersymmetry was introduced. For Landau-Ginzburg models it gives a
Morse-theoretical description of the corresponding $A_{\infty}$-category
of A-branes. It turns out that the combinatorial part of their work admits
a higher-dimensional generalization. I am going to discuss that
generalization, its relation to Gaiotto-Moore-Witten's work and speculate
about possible applications.
