Is it legal to publish a book written by AI?

Good day, I'm curious to know whether it's legal to publish a book that has been authored solely by an AI system? I understand that the field of artificial intelligence is rapidly evolving, and I'm wondering if there are any existing laws or regulations that govern the publication of AI-generated works. Additionally, I'm also interested in knowing if there are any potential copyright or authorship issues that may arise from publishing such a book. Could you please provide some clarity on this matter? Thank you.
