In this paper we compute topological invariants for some configuration spaces of complex projective spaces. We shall describe Sullivan models for these configuration spaces.
This article deals with the means of expressions of 'possibilty', 'necessity' and 'volition' in Novgorodian Birch Bark Letters. The author fives an overview of the different types of expressions and compares them with the modal inventory of Modern Russian. The analysis is based on a classification of the modal means of expression which takes both semantics and formal properties into account.
