Abstract.
Let X and Y be regular strictly semi-stable varieties over a discrete valuation ring R and let \( R \subseteqq {\widetilde {R}} \) be a finite ramified extension of discrete valuation rings. We explicitly give desingularization procedures for the base change \( X \times _R {\widetilde {R}} \) and for the product \( X \times _R Y \).
