Let k be a field, A a finite k-algebra and X a smooth A-scheme. We describe the Galois set of connected components of the Weil restriction of X along A/k in terms of the sets of connected components of the geometric fibers of X.

Abstract
Let k be a field, A a finite k-algebra and X a smooth A-scheme. We describe the Galois set of connected components of the Weil restriction of X along A/k in terms of the sets of connected components of the geometric fibers of X.
