The subject line is misleading. There is only one DDD so "DDD correctly
emulated by HHH" should simply mean DDD and nothing else.

 That doesn't fix the subject line.
 

Then I don't understand what you are saying.
"DDD correctly emulated by HHH cannot possibly halt"
When halt means reaching its own final state and terminating normally.

Every time any HHH correctly emulates DDD it calls the
x86utm operating system to create a separate process
context with its own memory virtual registers and stack,
thus each recursively emulated DDD is a different instance.

 There should be a comma after the word "memory".
 

Yes.

Simulating Termination Analyzer H is Not Fooled by Pathological Input D
https://www.researchgate.net/publication/369971402_Simulating_Termination_Analyzer_H_is_Not_Fooled_by_Pathological_Input_D

 There is another error on the first page. The first sentence says: "The notion
of a simulating termination analyzer is examined at the concrete level of pairs
of C functions". That is contracited in the fourth paragraph: "To understand
this analysis requires a sufficient knowledge of the C programming language
and what an x86 emulator does". The analysis is not at the level of C functions
if any knowledge about an x86 emulator is needed.
 

That is a good idea. The less prerequisite knowledge my target
audience needs the more people will be able understand what I am
saying. I am trying to make my first page as simple as possible.
To understand this analysis requires a sufficient knowledge
of the C programming language. An x86 emulator works just
like a C language interpreter except that it uses the compiled
machine language of a function instead of its source-code.
That HHH is built from an x86 emulator allows it to simulate
other C functions as if it was a C language interpreter.
The second page will have the more difficult prerequisites.
