Let A$A$ be an integral complete local ring over a field which is complete intersection.

Let B$B$ be a normalization of A$A$.

Q. Is B gorenstein$B$ Gorenstein?

I guess that even the normalization of gorensteinGorenstein local ring should be gorensteinGorenstein.

Normalization of complete intersection

Let A be an integral complete local ring over a field which is complete intersection.

Let B be a normalization of A.

I guess that even the normalization of gorenstein local ring should be gorenstein.
