Is it safe to implant bioresorbable scaffolds in ostial side-branch lesions? Impact of 'neo-carina' formation on main-branch flow pattern. Longitudinal clinical observations [PDF]
, 2015 Formation of a 'neo-carina' has been reported after bioresorbable vascular scaffolds (BVS) implantation over side-branches. However, as this 'neo-carina' could protrude into the main-branch, its hemodynamic impact remains unknown. We present two cases of

Iwasawa's Local Splitting Theorem for Pro-Lie Groups
, 2008 If the nilradical 𝔫(𝔤) of the Lie algebra 𝔤 of a pro-Lie group G is finite dimensional modulo the center 𝔷(𝔤), then every identity neighborhood U of G contains a closed normal subgroup N such that G/N is a Lie group and G and N × G/N are locally ...

Spectral multipliers on Lie groups of polynomial growth
, 1994 Let L be a left invariant sub-Laplacian on a connected Lie group G of polynomial volume growth, and let {EA, )A*> O} be the spectral resolution of L and m a bounded Borel measurable function on [0, oo) .

Analysis and Geometry in Metric Spaces, 2018 Carnot groups are distinguished spaces that are rich of structure: they are those Lie groups equipped with a path distance that is invariant by left-translations of the group and admit automorphisms that are dilations with respect to the distance.

Examples of compact non-Kähler almost Kähler manifolds
, 1985 A parametrized family of compact non-Kihler almost Kihler manifolds M2r+2, r > 1, is constructed. For r odd, these manifolds are shown to have odd first Betti number, so they cannot be Kihlerian. Introduction. Few examples, compact or not, of non-Kaihler

Rank one lattices whose parabolic isometries have no rotational part
, 1998 We prove a result on certain finite index subgroups of rank one lattices which is motivated by cusp closing constructions. Let X always denote a rank one symmetric space of non-compact type, i.e., X is the hyperbolic space KH, n ≥ 2, where K is either R ...

, 1981 Let L be a left invariant differential operator on the nilpotent Lie group N. It is shown that if 7r(L) is invertible for all irreducible representations ir in general position (and if the inverses satisfy some mild technical conditions), then L is ...
