Let g be a finite dimensional complex semi-simple Lie algebra with Weyl group W and simple reflections S. For I ⊆ S let gI be the corresponding semi-simple subalgebra of g. Denote by WI the Weyl group of gI and let w◦ and w I ◦ be the longest elements of W and WI , respectively. In this paper we show that the answer to Kostant’s problem, i.e. whether the universal enveloping algebra surjects on...
Let g be a finite dimensional complex semi-simple Lie algebra with Weyl group W and simple reflections S. For I ⊆ S let g I be the corresponding semi-simple subalgebra of g. Denote by W I the Weyl group of g I and let w • and w I • be the longest elements of W and W I , respectively. In this paper we show that the answer to Kostant's problem, i.e. whether the universal enveloping algebra surjec...
We assessed the safety and feasibility of various stenting techniques using the sirolimus-eluting stent (SES) in the treatment of unprotected left main coronary artery (LMCA) bifurcation stenoses. One hundred sixteen patients with unprotected LMCA bifurcation stenoses underwent SES implantation. A simple stenting technique (simple group, n = 67) across the left circumflex artery (LCx) and a com...

We show that Y. Prokhorov’s “Simple Finite Subgroups of the Cremona Group of Rank 3” implies that, over any field of characteristic 0, the essential dimensions of the alternating group, A7, and the symmetric group, S7, are 4.
