Hans Kung | Encyclopedia

Hans Küng. Hans Küng (born 1928), a Swiss Roman Catholic theologian, questioned church dogma, emphasized the need for reform within the church, and sought reunion with other Christian groups. His liberal views led to his censorship by the Vatican in 1979. Hans Küng was born on March 19, 1928, in Sursee, Switzerland.

convex optimization

$begingroup$ @Rufus Linear cones and quadratic cones are both bundle of lines connecting points on the interior to a special convex subset of the cone. For a typical quadratic cone that's the single point at the "apex" of the cone. Informally linear cones are similar but have hyper-plane boundaries instead of hyper-circles. $endgroup$

Matrices leaving a cone invariant

For a subset S of a cone K, the intersection of all faces of K including S is called the face of K generated by S and is denoted by '(S).If S = fxg, then '(S) is written simply as '(x).For faces F;G of K, their meet and join are given respectively by F^G = FG and F _G = '(F [G). A vector x 2 K is an extreme vector if either x is the zero vector or x is nonzero and '(x) = f‚x : ‚ ‚ 0g ...

It's called the second order cone because it's defined by a quadratic equation rather than a linear one. This naming is consistent with a quadratic polynomials being of degree two while a linear polynomial is of degree one.
