The study of the distribution of real roots of a polynominal with random coefficients, which traces back at least to [BP32], has recently been developed in the direction of multivariate systems. This paper studies the more general case of mixed multihomogeneous systems.

We propose a model of a random normal game for given (finite nonempty) sets of players and pure strategies; this model is shown to be canonical in a certain sense.

The goal of this paper is to construct a user-friendly model of unawareness. We start from an axiom system (in first-order modal logic) that enables us to express the following kinds of sentences: “the agent is not sure whether or not there is anything that he is unaware of”, and “I am not...
