Abstract:
Integration over connection type variables in the path integral for the discrete form of the first-order formulation of general relativity theory is studied. The result (a generalized function of the rest of variables of the type of tetrad or elementary areas) can be defined through its moments, i.e. integrals of it with the area tensor monomials. In our previous paper these moments have been defined by deforming integration contours in the complex plane as if we had passed to a Euclidean-like region. In this paper we define and evaluate the moments in the genuine Minkowski region. The distrib

Abstract:
In this thesis we have introduced a real space morphological tool, Contour Minkowski tensor (CMT) to analyse the 21cm brightness temperature field from EoR. We showed that the size and shape information of structures encoded by the eigenvalues of CMT enable us to extract maximum information from minimum number of morphological descriptors. We devised a statistical framework which will help us answer a plethora of physical questions required to model EoR with upcoming 21cm observations. We showed that we can infer bubble size information, ionization history and astrophysical properties of
