چکیده
The notion of a formally smooth bimodule is introduced and its basic properties are analyzed. In particular it is proven that a B-A bimodule M which is a generator left B-module is formally smooth if and only if the M-Hochschild dimension of B is at most one. It is also shown that modules M which are generators in the category σ[M ] of M-subgenerated modules provide natural examples of formally smooth bimodules.

This paper encloses a complete and explicit description of the derivations of the Lie algebra D(M) of all linear differential operators of a smooth manifold M , of its Lie subalgebra D 1 (M) of all linear first-order differential operators of M , and of the Poisson algebra S(M) = Pol(T * M) of all polynomial functions on T * M, the symbols of the operators in D(M). It turns out that, in terms o...

Finite quantum groupoids can be described in many equivalent ways [8, 11, 16]: In terms of the weak Hopf C -algebras of Böhm, Nill, and Szlachányi [2] or the finite-dimensional Hopf-von Neumann bimodules of Vallin [14], and in terms of finite-dimensional multiplicative partial isometries [4] or the finite-dimensional pseudo-multiplicative unitaries of Vallin [15]. In this note, we show that in ...

We study the convergence properties of alternating proximal minimization algorithms for (nonconvex) functions of the following type: L(x, y) = f(x) + Q(x, y) + g(y) where f : R → R∪{+∞} and g : R → R∪{+∞} are proper lower semicontinuous functions and Q : R×R → R is a smooth C (finite valued) function which couples the variables x and y. The algorithm is defined by: (x0, y0) ∈ R n × R given, (xk...

A number of recent papers concerned various non-degeneracy conditions on embedding and immersions of smooth manifolds in affine and projective spaces defined in terms of mutual positions of the tangent spaces at distinct points, see [1, 2, 3, 4, 6, 7, 9]. Following Ghomi [1], a C-embedded manifold M ⊂ R is called T -embedded if the tangent spaces to M at distinct points do not intersect. For ex...
