The discussion in the chat group continued.
Zhang Zhen was talking about the difficulties he encountered in researching robot operating systems, and several people joined the discussion.
Zhao Yi pretended not to see the chat records and silently sent a smiling emoticon.
A few seconds later, Ma Xiaojun typed and asked, "Zhao Yi, I saw your interview video. Your fourth paper will be published in 'Mathematical Progress' next month, right?"
"Yes, it has been accepted."
"Is your paper about twin primes? That's what your interview mentioned."
"Yes."
"Can you tell us more about it?"
Zhao Yi replied, "It's a weakened version of the twin prime conjecture. I only proved a small part of it, but I think this approach to prove the twin prime conjecture has reached a dead end."
"Oh."
