Classical gravitational anomalies of Liouville theory
We show that for classical Liouville field theory, diffeomorphism invariance, Weyl invariance and locality cannot hold together. This is due to a genuine trace, in curved space. Our focus is on a field -independent term, pr...

Description of Thickness Variability by Fractal Dimension
The application of fractal dimension for description of roughness of thickness profile curve is described. The scale invariant ftactel dimension is in the interval from 1 (smooth curve) to 2 (limiting roughness). For estima...

Generalizations of pp-wave spacetimes in higher dimensions.
We investigate D-dimensional Lorentzian spacetimes in which all of the scalar invariants constructed from the Riemann tensor and its covariant derivatives are zero. These spacetimes are higher-dimensional generalizations of D-dimensional pp-...

Non-separable rotation moment invariants
In this paper, we introduce new rotation moment invariants, which are composed of non-separable Appell moments. We prove that Appell polynomials behave under rotation as monomials, which enables easy construction of the invariants. ...
