Abstract: This article is on the inverse Galois problem in Galois theory of linear iterative differential equations in positive characteristic. We show that it has an affirmative answer for reduced algebraic group schemes over any iterative… read more here.

Abstract: Abstract We give new characterizations to ensure that a free product of groups with amalgamation has a simple reduced group C ⁎ -algebra, and provide a concrete example of an amalgam with trivial kernel, such… read more here.
