  Group 6 element - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-10-20)
A Group 6 element is the series of elements in group 6 (IUPAC style) in the periodic table, which consists of the transition metals chromium (Cr), molybdenum (Mo), tungsten (W), and seaborgium (Sg).
"Group 6" is the new IUPAC name for this group, the old style name was "group VIA" in the old European system or "group VIB" in the old US system.
Group 6 must not be confused with the group with the old-style group names of either VIB (European system) or VIA (US system) which is now group 16.

 MSN Encarta - Search View - Element 116
Isotopes are varieties of an element that all contain the same number of protons in their cores but contain different numbers of neutrons.
Elements in the same group of the periodic table often share similar properties (a pattern known as the periodic law).
Ununhexium is a temporary name based on the element’s atomic number that uses Latin prefixes for the digits of the atomic number (un = 1, hex = 6) followed by the suffix -ium.

 element 105   (Site not responding. Last check: 2007-10-20)
More recently, it was reported that early in 1970 Dubna scientists synthesized Element 105 and that by the end of April 1970 "had investigated all the types of decay of the new element and had determined its chemical properties." The Soviet group proposed the name joliotium for Element 105.
While the first atoms of Element 105 are said to have been detected conclusively on March 5, 1970, there is evidence that Element 105 had been formed in Berkeley experiments a year earlier by the method described.
Element 261-105 was produced both by bombarding 250Cf with 15N and by bombarding 249Bk with 16-O. The isotope emits 8.93-MeV alpha particles and decays to 257Lr with a half-life of about 1.8 s.

The first element to be discovered by means of its radioactivity, polonium was found in pitchblende in 1898 by the French chemist Marie Curie, who named it for her native country, Poland.
Polonium is one of the elements in the uranium-radium series of radioactive decay, the first member of which is uranium-238.
Polonium is used in nuclear research with elements such as beryllium that emit neutrons when bombarded by alpha particles.

If you want to know the automorphisms of GL_n(K) as an abstract group, it might be strange because, for instance any automorphism of K as a field would provide an automorphism of GL_n(K).
But, if you want to know the group of automorphism of GL_n(K) as an algebraic group defined over K then the answer is more interesting (as far as i am concerned).
If we denote by G the group of automorphisms of GL_n(K) (as an algebraic group), I claim that we have the following split exact sequence of groups : 1 -> Gl_n(k)/diagonal invertible matrices -> G -> Z/2Z -> 1 (where the non trivial element of Z/2Z act on GL_n(k)/k^* by the formula g -> transpose(g^-1)).

The variational approximation is based on computing a certain weighted average of a finite element approximation to the solution of the Navier-Stokes equations.
Our main result is an a posteriori estimate that puts a bound on the error in the lift and drag coefficients in terms of the local mesh size, a local residual quantity, and a local weight describing the local stability properties of an associated dual problem.
The error bound is thus computable and can be used for quantitative error estimation; we apply it to design an adaptive finite element algorithm specifically for the approximation of the lift and drag coefficients.
