Topology change in quantum gravity is considered. An exact wave function of the Universe is calculated for topological Chern-Simons 2+1 dimensional gravity. This wave function occurs as the effect of a quantum anomaly which leads to the induced gravity. We find that the wave function depends universally on the topology of the two-dimensional space. Indeed, the property of the ground state wave ...

For a classical superconformal gauge theory in a conformal supergravity background, its chiral R-symmetry anomaly, Weyl anomaly and super-Weyl anomaly constitute a supermultiplet. We review how these anomalies arise from the five-dimensional gauged supergravity in terms of the AdS/CFT correspondence at the gravity level. The holographic production of this full superconformal anomaly multiplet p...

Linear anomalies are important in the interpretation of gravity and magnetic data because they indicate some important structural features. In this study, a method is proposed to extract lineaments which may be difficult to recognize. It is based on the convolution between the templates obtained from the second horizontal derivative of the theoretical anomaly due to a truncated horizontal plate...

We study effects associated with the chiral anomaly for a cascading SU(N+ M)×SU(N) gauge theory using gauge/gravity duality. In the gravity dual the anomaly is a classical feature of the supergravity solution, and the breaking of the U(1) R-symmetry down to Z2M proceeds via the Higgs mechanism.

This study uses the gravity method to assess characteristics of Manna segment fault, a part Sumatran fault. research aims contribute existing knowledge by providing additional insights into fault's characteristics, which is essential for future disaster mitigation efforts. The fault geographically situated between coordinates 4.4⁰S - 3.9⁰ S and 102.7⁰ E – 103.2⁰ E, making this area prone earthq...

Satellite altimetry has become an operational remote sensing technique with important applications to geodynamics. In the present paper, ocean floor topography and tectonic detection in the deep earth are investigated using gravity anomalies from global gravity models and satellite altimetry corrected for waveform distortions. We compute the spherical harmonic degree components of the gravity a...

The loop quantum gravity technique is applied to the free bosonic string. A Hilbert space similar to loop space in loop quantum gravity as well as representations of diffeomorphism and hamiltonian constraints on it are constructed. The string in this representation can be viewed as a set of interacting relativistic particles each carrying a certain momentum. Two different regularizations of the...

It is shown that conformal matter with cL 6= cR can be consistently coupled to two-dimensional ‘frame’ gravity. The theory is quantized in conformal gauge, following David, and Distler and Kawai. There is no analogue of the c = 1 barrier found in nonchiral non-critical strings. A non-critical heterotic string is constructed—it has 744 states in its spectrum, transforming in the adjoint represen...
