Seasonal Mass Changes and Crustal Vertical Deformations Constrained by GPS and GRACE in Northeastern Tibet
Surface vertical deformation includes the Earth's elastic response to mass loading on or near the surface. Continuous Global Positioning System (CGPS) stations record such deformations to estimate seasonal and secular mass changes. We used 41 CGPS stations to construct a time series of coordinate changes, which are decomposed by empirical orthogonal functions (EOFs), in northeastern Tibet. The ...
متن کاملCrustal Deformations in the Mediterranean Area Computed from SLR and GPS Observations
Space geodesy provides an efficient technique to determine contemporary crustal deformations. This paperdiscusses the computation of tectonic motions in the Mediterranean area from observationsacquired by Satellite Laser Ranging (SLR) and Global Positioning System (GPS) instruments. The SLR contribution is based on measurements on LAGEOS-1,taken in the period September 1983 to December 1992. Fo...
متن کاملOn Conformal Deformations
For a conformal theory it is natural to seek the conformal moduli space, Mc to which it belongs, generated by the exactly marginal deformations. By now we should have the tools to determine Mc in the presence of enough supersymmetry. Here it is shown that its dimension is determined in terms of a certain index. Moreover, the D-term of the global group is an obstruction for deformation, in prese...
متن کاملOn Graded Bialgebra Deformations
We introduce the graded bialgebra deformations, which explains Andruskiewitsch-Schneider’s liftings method. We also relate this graded bialgebra deformation with the corresponding graded bialgebra cohomology groups, which is the graded version of the one due to Gerstenhaber-Schack.
متن کاملOn Generalized Abelian Deformations
We study sun-products on R, i.e. generalized Abelian deformations associated with star-products for general Poisson structures on R. We show that their cochains are given by differential operators. As a consequence, the weak triviality of sun-products is established and we show that strong equivalence classes are quite small. When the Poisson structure is linear (i.e., on the dual of a Lie alge...
