Hi All,
I've taken a long hiatus to focus on my day job, designing Power-PC microprocessors, for IBM, most recently Power10. I'll try to log in every once in awhile and catch up on the post's that other's have made. But I can't promise I'll focus on it with my previous tetration intensity, but I am back to my tetration hobby, and catch up on some of the posts on this forum.

ps. no health or covid issues, just full time work and exercising enough to stay healthy. I'd still like to finish that paper on rigorously proving my matrix based version of fatou.gp converges to Kneser.

Great to hear you're healthy and keeping strong.
I can't wait to see your paper. I'm dying to read it!

Hi Sheldon -
happy seeing you back here!
Hope I'll see your paper soon and read it. However, my energy seem to have drown out much, so I couldn't for instance follow (and engage in) MPhlee's and James' conversation/exchange.
Perhaps we are able to continue our short sequence of zoom-meetings covering some basic (but relevant) stuff.
See/read you (CR/U :-) )

If you ever have any questions feel free to ask, Gottfried. Mphlee and I did go a bit off the deepend when discussing conjugacy classes/category theory though... I still have more questions than answers, and I'm sure Mphlee feels the same way, lol.
I'm sorry to hear about your medical issues. Stay strong and keep fighting

I'm happy to slow down my posts if it helps--it's not a problem at all. I'm happy to be supportive if you're feeling a little slow. It must be hard, and I'd like to be as supportive as I can. Thanks, for at least reading mine and Mphlee's posts. Sending my best wishes.
Regards, James

Keep strong buddy. Take time to let your body rest.
@Sheldon : Ofcourse we are welcoming the return of a tetration legend
We still have lots to discuss and many friendly battles to fight :p

I'm glad you're back. Many people have died or been left with permanent disabilities due to covid.
I have been worried that many people on the other end of the email will never be able to contact each other again because of covid.

That's very sad. I'm one of the lucky ones who could isolate and quarantine comfortably with no real worries. I recently learned one of my favourite professors at University of Toronto succumbed to covid.
