e. In mathematics, the special linear Lie algebra of order n over a field , denoted or , is the Lie algebra of all the matrices (with entries in ) with trace zero and with the Lie bracket given by the commutator. This algebra is well studied and understood, and is often used as a model for the study of other Lie algebras.
21440. Anatomical terminology. [ edit on Wikidata] The sacroiliac joint or SI joint ( SIJ) is the joint between the sacrum and the ilium bones of the pelvis, which are connected by strong ligaments. In humans, the sacrum supports the spine and is supported in turn by an ilium on each side. The joint is strong, supporting the entire weight of ...
2.5–15% (US) [ 4] Restless legs syndrome, also known as restless leg syndrome ( RLS ), also known as Willis–Ekbom disease ( WED ), is a neurological disorder, usually chronic, that causes an overwhelming urge to move one's legs. [ 2][ 10] There is often an unpleasant feeling in the legs that improves temporarily by moving them. [ 2]
SU (2) is the universal covering group of SO (3), and so its representation theory includes that of the latter, by dint of a surjective homomorphism to it. This underlies the significance of SU (2) for the description of non-relativistic spin in theoretical physics; see below for other physical and historical context.
The Lie algebra of SL (2, R ), denoted sl (2, R ), is the algebra of all real, traceless 2 × 2 matrices. It is the Bianchi algebra of type VIII. The finite-dimensional representation theory of SL (2, R) is equivalent to the representation theory of SU (2), which is the compact real form of SL (2, C ).
SL.I (Type A) The Schütte-Lanz airship SL.I was the first of 20 airships built by the company. Construction was carried out in a large hangar at Rheinau near Mannheim. The ship was powered by four 125 hp (127 PS; 93 kW) Daimler-Benz engines installed in two ventral gondolas. A distinctive feature of the Schütte-Lanz ships was that the frame ...
The finite-dimensional representation theory of the noncompact group SL (2, R) is equivalent to the representation theory of SU (2), its compact form, essentially because their Lie algebras have the same complexification and they are "algebraically simply connected". (More precisely, the group SU (2) is simply connected and, although SL (2, R ...
Sri Lanka played their first Twenty20 International (T20I) match at the Rose Bowl, on 15 June 2006, against England, winning the match by 2 runs. [36] In 2014, they won the 2014 ICC World Twenty20 , defeating India by 6 wickets.
