Аннотация:
We consider relations in Grassmann algebra corresponding to the four-dimensional Pachner move 3–3, assuming that there is just one Grassmann variable on each 3-face, and a 4-simplex weight is a Grassmann–Gaussian exponent depending on these variables on its five 3-faces. We show that there exists a large family of such relations; the problem is in finding their algebraic-topologically meaningful parameterization. We solve this problem in part, providing two nicely parameterized subfamilies of such relations. For the second of them, we further investigate the nature of some of its parameters: they turn out to correspond to an exotic analogue of middle homologies. In passing, we also provide the 2–4 Pachner move relation for this second case.
