On the construction of a finite Siegel space

In this note we construct a finite analogue of classical Siegel's Space. Our approach is to look at it as a non commutative Poincare's half plane. The finite Siegel Space is described as the space of Lagrangians of a $2n$ dimensional space over a quadratic extension $E$ of a finite base field $F$. The orbits of the action of the symplectic group $Sp(n,F)$ on Lagrangians are described as homogeneous spaces. Also, Siegel's Space is described as the set of anti-involutions of the symplectic group.2

Acquisition of Real Estate in Mexico by U.S. Citizens and American Companies

Buying real estate in Mexico, or enjoying the beneficiary rights through a real estate trust, known in Mexico as fideicomiso, involves a considerable amount of money and effort. One must take into account that this legal transaction is executed in Mexico in accordance with Mexican law-a foreign legal system belonging to the civil legal tradition, contrasted by the U.S. legal system derivative of the common law tradition-and recognize that Americans and U.S. legal entities are typically quite unfamiliar with Mexican law. This Article provides a complete overview of the process of acquiring real estate in Mexico by Americans and U.S. companies in both the Restricted Zone and in the area situated outside the Restricted Zone, named here as the Permitted Zone for practical purposes
