Abstract

In this paper, we introduce a geometric structure that is capable of describing
matter and forces simultaneously. This structure can be established by using
the notion of Z2
-graded Lie algebroid structures and graded semi-Riemannian
metrics on them. Using calculus of variations, we derive field equations
from the extended Hilbert-Einstein action. The derived equations contain
Yang-Mills and Einstein field equations simultaneously. The even part of the
graded Lie algebroid describes forces and its odd part is related to matter
and particles.
