Today, invariant theory is often understood as a branch of representation theory, algebraic geometry, commutative algebra, and algebraic combinatorics. Each of these four disciplines has roots in nineteenth-century invariant theory. […] In modern terms, the basic problem of invariant theory can be categorized as follows. Let V be a K-vector space on which a group G acts linearly. In the ring of polynomial functions K[V] consider the subring K[V]ᴳ consisting of all polynomial functions on V which are invariant under the action of the group G. The basic problem is to describe the invariant ring K[V]ᴳ. In particular, we would like to know whether K[V]ᴳ is finitely generated as a K-algebra and, if so, to give an algorithm for computing generators.

The will to convene this Summit of the peoples and alternatives is based on a call (www.altersummit.eu ) that identifies the fundamentally political dimension of the EU crisis : the austeritarian answers are chosen knowingly although they aggravate the crisis, to impose a failover of the social order to an ultra-liberal model - at the cost of millions of jobs, abrupt social decline and significant threats to democracy itself.
