The report of the European Commission from October last year regarding Romania, has underlined a series of key domains in which the country still has to make progresses for the integration in the EU. The most important aspect continues to be the intensification need of the fight against...

Local systems are conglomerations of municipalities held together by commuting links. ? Are they real life objects or the result of some cryptic algorithm? Real life objects. Real life cities, to be precise, even if not made of brick and mortar, but of relationships. Relationships is the matter...

Suppose R is the complement of an essential arrangement of toric hyperlanes in the complex torus (C*)n and pi = pi1(R). We show that H*(R; A) vanishes except in the top degree n when A is one of the following systems of local coefficients: (a) a system of nonresonant coefficients in a complex...

Suppose R is the complement of an essential arrangement of toric hyperlanes in the complex torus and ? = ?1(R). We show that H*(R;A) vanishes except in the top degree n when A is one of the following systems of local coefficients: (a) a system of nonresonant coefficients in a complex line...
