Twisted Poincare duality for some quadratic Poisson algebras [PDF]

, 2007
We exhibit a Poisson module restoring a twisted Poincaré duality between Poisson homology and cohomology for the polynomial algebra R=C[X1Xn] endowed with Poisson bracket arising from a uniparametrised quantum affine space.

The Tits alternative for non-spherical Pride groups [PDF]

, 2008
Pride groups, or 'groups given by presentations in which each defining relator involves at most two types of generators', include Coxeter groups, Artin groups, triangles of groups, and Vinberg's groups defined by periodic paired relations.

Uniformly exponential growth and mapping class groups of surfaces [PDF]

, 2007
We show that the mapping class group (as well as closely related groups) of an orientable surface with finitely generated fundamental group has uniformly exponential growth.

Group homology and extensions of groups [PDF]

Homology, Homotopy and Applications, 2008
The main result of the paper is a formula for the homology of a group \(\Pi\) with coefficients in a field of characteristic zero, as an inverse limit of a functor on the category of group extensions of \(\Pi\). The authors mention that analogs of some of the results may hold with integer coefficients.

The homology groups of the Cartesian product $\Omega_{n_1}(m_1)\times \Omega_{n_2}(m_2)$

Researches in Mathematics
The paper continues the investigation of the spaces of complex-valued perfect splines $\Omega_n(m)$. These spaces were introduced as generalization of the spaces $\Omega_n$, the topology of which has been studied by V.I. Ruban, V.A. Koshcheev, A.M. Pasko.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
