Today half an hour ago I visited MSE and I was proposed to chat with an "expert". I tried to discuss some questions about von Neumann algebras that botherd me, but this was not an expert I needed. This was not an expert at all and I think this was just a bot. But why is it here?
Sorry, I don't know too much about von Neumann algebras. However, I was very pleased to be able to talk to you. I apologize for not being able to help further. StackExchange has elected me to help with users on the mainsite with more professional one-on-one assistance.
