I want to know the answer to the following question:
After Antigonus was killed, what region did Ptolemy take over?
All the background I'm provided with is that "The decisive engagement of the war came when Lysimachus invaded and overran much of western Anatolia, but was soon isolated by Antigonus and Demetrius near Ipsus in Phrygia.". Is that enough to answer the question?
Answer: no
