On the exponential map of almost simple real algebraic groups.
Let A be a finite-dimensional algebra over an algebraically closed field with radical square zero, and such that all simple A-modules have dimension at most two. We give a characterization of those A that have finitely many conjugacy classes of left ideals.
We present an algorithm for computing the greatest integer that is not a solution of the modular Diophantine inequality , with complexity similar to the complexity of the Euclid algorithm for computing the greatest common divisor of two integers.
