We establish that, given Σ a compact orientable surface, and G a finitely presented one-ended group, the set of copies of G in the mapping class group MCG(Σ) consisting of only pseudo-Anosov elements except identity, is finite up to conjugacy. This relies on a result of Bowditch on the same problem for images of surfaces groups. He asked us whether we could reduce the case of one-ended groups t...

The planar [maximum deviation 0.0066 (4) Å] symmetrical mol-ecule of the title compound, C(10)H(6)S(2), lies across a crystallographic inversion centre. The thio-phene rings are rotationally disordered about the acetyl-ene bond, with the two pseudo inversion-related S atoms in 0.80:0.20 occupancy sites. The C C bond distance is 1.195 (9) Å.

The title compound, [RuCl(2)(C(10)H(14))(C(6)H(6)FN)], a pseudo-octa-hedral d(6) complex, has the expected piano-stool geometry around the Ru(II) atom. The fluoro-aniline ring forms a dihedral angle of 19.3 (2)° with the p-cymene ring. In the crystal, two mol-ecules form an inversion dimer via a pair of N-H⋯Cl hydrogen bonds. Weak inter-molecular C-H⋯Cl inter-actions involving the p-cymene ring...

this paper describes a methodology for the integration of well logs and a series of grid-based attributes extracted from interpreted seismic data for prediction of porosity distributions. the studied area is located in the southwest iran. before finding a relationship between the target logs and predicted logs from 3d seismic data, we have interpreted the 3d seismic data in the studied area. al...

Various Green’s functions occurring in Poisson potential field theory can be used to construct non-orthogonal, non-compact, continuous wavelets. Such a construction leads to relations between the horizontal derivatives of geophysical field measurements at all heights, and the wavelet transform of the zero height field. The resulting theory lends itself to a number of different applications in t...

In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...

We introduce C∗-pseudo-multiplicative unitaries and (concrete) Hopf C∗-bimodules, which are C∗-algebraic variants of the pseudo-multiplicative unitaries on Hilbert spaces and the Hopf-von Neumann-bimodules studied by Enock, Lesieur, and Vallin [5, 6, 4, 10, 19, 20]. Moreover, we associate to every regular C∗-pseudo-multiplicative unitary two Hopf-C∗bimodules and discuss examples related to loca...

We study the stability of compact pseudo-Kähler manifolds, i.e. complex manifolds X endowed with a symplectic form compatible structure X. When corresponding metric is positive-definite, Kähler and any sufficiently small deformation admits by well-known result Kodaira Spencer. prove that surfaces are also stable, but we show fails in every dimension n≥3. Similar results obtained for neutral Cal...
