For a pair of divergence-free vector fields B and \( \tilde B \) respectively localized in two oriented tubes U and \( \tilde U \) in ℝ3, we propose a fourth-order integral W and describe the dependence between the integral W and a higher topologic

We prove that the current helicity integral for a thin magnetic tube is directly proportional to the twist Tw of field lines, which appears in the Calugarianu formula as a summand. Using this approach, we analyze the law of the variation of magnetic

In the problem of estimating the number of longitudinal normals of elastic waves in crystals, several approaches based on the methods of modern topology and associated with the use of topological invariants are proposed. It is shown that for any symm
