P. Kuusk et E. Paal, SOME APPLICATIONS OF GEODESIC LOOPS AND NONLINEAR GEOMETRIC ALGEBRA IN THE THEORY OF GRAVITY, Acta applicandae mathematicae, 50(1-2), 1998, pp. 67-76
Algebraic systems called local geodesic loops and their tangent Akivis
algebras are considered. Their possible role in the theory of gravity
is discussed. Quantum conditions for infinitesimal quantum events are
proposed.
