TORSION, DILATON AND GAUGE COUPLINGS
, 2006
"... NonAbelian gauge fields are traditionally not coupled to torsion due to violation of gauge invariance. However, it is possible to couple torsion to YangMills fields while maintaining gauge invariance provided one accepts that the gauge couplings then become scalar fields. In the past this has been ..."

in the universe. With this scenario, we argue that the very early universe provides a RiemannCartan geometry with nonzero torsion coupling to gauge fields. The torsion is just the derivative of gauge coupling (scalar) fields. As a result, in the evolution of the Universe, when the scalar (moduli) fields
TORSION AND CURVATURE ELEMENTS OF ANY ORBIT FROM ECE THEORY by
"... The Minkowski metric constrained by any orbit is shown to produce nonzero torsion and curvature elements in general for any orbit, or for any rotational motion in a plane. This is a new general relativity that describes all orbits self consistently in terms of Cm·tan's geometry, the basis for ..."

The Existence of Supersymmetric String Theory with Torsion
, 2005
"... ... Strominger and Witten took the matric product of a maximal symmetric four dimensional spacetime M with a six dimensional Calabi–Yau vacua X as the ten dimensional spacetime; they identified the Yang–Mills connection with the SU(3) connection of the Calabi– Yau metric and set the dilaton to be a ..."

He considered a ten dimensional spacetime that is the product M ×X of a maximal symmetric four dimensional spacetime M and an internal space X; themetricon M × X takes
Torsionfree abelian group rings III
 Bull. Fac. Sci., Ibaraki Univ
, 1977
"... In this paper a ring is a commutative ring with identity. Let X be an indeterminate, G a nonzero torsionfree abelian group (additively written). We consider the group ring AG[X] of G over a ring A. AG[X] is the ring of elements ƒ°aaXa, aa•¸A, a•¸G almost all aa are zero. This paper is a continua ..."

PROOF OF THE ANTISYMMETRY OF THE CHRISTOFFEL. CONNECTION FROM THE CART AN IDENTITY
"... By considerations of the Cartan identity of differential geometry, it is proven conclusively that the Christoffel cmmection is always antisymmetric for non zero torsion and curvature. This proof overturns a century of dogma which asserted arbitrarily that the Christoffel connection is symmetric. The ..."

LETTER TO THE EDITOR The shapes of selfavoiding polygons with torsion
, 1997
"... Abstract. We consider selfavoiding polygons on the simple cubic lattice with a torsion fugacity. We use Monte Carlo methods to generate large samples as a function of the torsion fugacity and the number of edges in the polygon. Using these data we investigate the shapes of the polygons at large tor ..."

TORSION AND NONMETRICITY IN SCALARTENSOR THEORIES OF GRAVITY BY
, 1993
"... We show that the gravitational field equations derived from an action composed of i) an arbitrary function of the scalar curvature and other scalar fields plus ii) connectionindependent kinetic and source terms, are identical whether one chooses nonmetricity to vanish and have nonzero torsion or v ..."

"... In this paper, the knotlike cosmic strings in the early universe are discussed. We derive the cosmic string structures from the nonzero torsion tensor, and reveal that these strings are just created from the zero points of complex scalar quintessence field. In these strings we mainly study the knot ..."
