A new set of infinitesimal transformations generalizing scale invariance for strongly anisotropic critical systems is considered. It is shown that such a generalization is possible if the anisotropy exponent \theta =2/N, with N=1,2,3 ... Differential equations for the two-point function are derived and explicitly solved for all values of N. Known special cases are conformal invariance (N=2) and Schr\"odinger invariance (N=1). For N=4 and N=6, the results contain as special cases the exactly known scaling forms obtained for the spin-spin correlation function in the axial next nearest neighbor spherical (ANNNS) model at its Lifshitz points of first and second order.

  1. Perfect fluid equations with nonrelativistic conformal supersymmetries

    hep-th 2026-05 unverdicted novelty 5.0 of 10

    Constructs supersymmetric perfect fluid equations for N=2 conformal Newton-Hooke and N=1 l-conformal Galilei superalgebras using Hamiltonian methods with anticommuting superpartner fields for density and velocity.

  2. Perfect fluid equations with nonrelativistic conformal symmetry: Exact solutions

    math-ph 2026-04 unverdicted novelty 5.0 of 10

    Exact solutions to perfect fluid equations are built via invariance under Schrödinger, l-conformal Galilei, or Lifshitz groups, producing Bjorken-like velocity fields with tunable high-density peaks.

  3. On the instability of some upward propagating, exact, nonlinear mountain waves

    physics.ao-ph 2026-04 unverdicted novelty 5.0 of 10

    Exact dry-adiabatic mountain waves are linearly unstable for steepness above 1/3, with an unstable layer beneath the tropopause.

  4. Remarks on Galilean electromagnetism

    physics.class-ph 2026-01 unverdicted novelty 4.0 of 10

    The electric and magnetic nonrelativistic limits of Maxwell's equations with sources are invariant under the ℓ-conformal Galilei group for any half-integer ℓ, and this symmetry permits unphysical accelerating solutions.
