Beyond the Lambertian Assumption: A generative model for Apparent BRDF fields of Faces using AntiSymmetric Tensor Splines ∗
"... Human faces are neither exactly Lambertian nor entirely convex and hence most models in literature which make the Lambertian assumption, fall short when dealing with specularities and cast shadows. In this paper, we present a novel antisymmetric tensor spline (a spline for tensorvalued functions) b ..."

Biquaternion formulation of relativistic tensor dynamics
"... In this paper we show how relativistic tensor dynamics and relativistic electrodynamics can be formulated in a biquaternion tensor language. The treatment is restricted to mathematical physics, known facts as the Lorentz Force Law and the Lagrange Equation are presented in a relatively new formalism ..."

formalism. The goal is to fuse antisymmetric tensor dynamics, as used for example in relativistic electrodynamics, and symmetric tensor dynamics, as used for example in introductions to general relativity, into one single formalism: a specific kind of biquaternion tensor calculus.
and Rmatrices with a new parameter
, 2003
"... In this paper, using a quantum superalgebra associated with the universal central extension of sl(2,2) (1) , we introduce new Rmatrices having an extra parameter x. As x → 0, they become those associated with the symmetric and antisymmetric tensor products of the copies of the vector representatio ..."

Nonlinear Realization of Lorentz Symmetry
, 2000
"... We explore a nonlinear realization of the (2+1)dimensional Lorentz symmetry with a constant vacuum expectation value of the second rank antisymmetric tensor field. By means of the nonlinear realization, we obtain the lowenergy effective action of the NambuGoldstone bosons for the spontaneous Lor ..."

Spontaneous Lorentz Symmetry Breaking
, 2001
"... We study the spontaneous Lorentz symmetry breaking in a field theoretical model in (2+1)dimension, inspired by string theory. This model is a gauge theory of an antisymmetric tensor field and a vector field (photon). The NambuGoldstone (NG) boson for the spontaneous Lorentz symmetry breaking is i ..."

Supersymmetric Extension of the NonAbelian ScalarTensor Duality
, 2001
"... The field theory dual to the FreedmanTownsend model of a nonAbelian antisymmetric tensor field is a nonlinear sigma model on the group manifold G. This can be extended to the duality between the FreedmanTownsend model coupled to YangMills fields and a nonlinear sigma model on a coset space G/H. ..."

Free totally (anti)symmetric massless fermionic fields in ddimensional antide Sitter space
, 1997
"... Free massless fermionic fields of arbitrary spins s> 0 corresponding to totally (anti)symmetric tensorspinor representations of the SO(d − 1) compact subgroup and in ddimensional antide Sitter space are investigated. We propose the free equations of motion, subsidiary conditions and correspond ..."

The Mirror Transform of Type I Vacua in Six Dimensions
, 1997
"... We study certain compactifications of the type I string on K3. The three topologically distinct choices of gauge bundle for the type I theory are shown to be equivalent to type IIB orientifolds with different choices of background antisymmetric tensor field flux. Using a mirror transformation, we r ..."
