The role of geometric effects in the quantum theory of particles and fields and spacetime has been an active topic of research. This paper attempts to obtain the conditions for a Unified Gauge field theory , including gravity. In the Yang Mills type of theories with compactification from a 10 or 11 dimensional space to spacetime of 4 dimensions , the Kaluza Klein and the Holonomy approach has been used. In the compactification of Calabi Yau spaces and sub manifolds the Euler number Topological index is used to label the allowed states and the transitions. With a SU(2) or SL(2,C) connection for gravity and the U(1)*SU(2)*SU(3) or SU(5) connection for the other interactions, a Unified gauge field theory is expressed in the 10 or 11 dimensional space. Partition functions for the sum over all possible configurations of sub spaces labeled by Euler number index and Action for gauge and matter fields are constructed. Topological Euler number changing transitions that can occur in the gauge fields and compactified spaces and their significance are discussed. The possible limits and effects of the physical validity of such a theory are discussed.
