Indeed it's ambiguous whether the question is about WW2. But especially, the question is about
mathematical research interrupted by the war, not just a list of mathematicians who were killed, or affected in any way. You can imagine math research interrupted by the war without somebody specifically killed, and imagine mathematicians killed but who were inactive at the time of war. Mentioning mathematicians killed (or interrupted in any way...) without mentioning what they were active about, does not, in my opinion, answer the question. —
