Dear Professor Mani:

First, sincere apologies for my careless error with respect to the direction of 
monotonicity by not specifying the system.  

I poised the question in this framework for educational purposes. Some peirce 
-l  list serve members have extremely narrow views of the nature of Prigoginian 
entropy in the philosophy of science and it relation to CSP's writings. .

Now, back to the points at hand, which is the relation between the term 
'entropy' as it originated in the 19th Century  and its role as scientific / 
mathematical fact with regard to heat flow and thermodynamics.  Within this 
framework, my interest is in chemical thermodynamics as it relates to chemical 
symbols of the Table of Elements hence to all living organisms. Entropy is an 
experimental measurement of heat capacity and heat flow. Furthermore, this 
logic of thermodynamics is intertwined with the Law Of Mass Action for chemical 
equations relating to chemical change.  As a mathematician / computer 
scientist, you are free to prune your world view to a narrower focus such that 
my interests are excluded . But, to the science of chemical engineering, the 
classical view of entropy is essential to the operations of the chemical 
industry, for example, petro-chamical manufacturing of fuels and plastics.  

Now, turning to your recommended reference to Lieb / Yngvason papers, for 
example, Current Developments in Mathematics, 2001, 89-129, (which is 
downloadable from the internet).

They explicitly state that (about entropy) in the abstract and text:

"This principle is independent of models, statistical mechanical or otherwise, 
and can be understood without recourse to to Carnot cycles, ideal gases, and 
other assumptions as 'heat', 'temperature', reversible processes, etc, as is 
usually done."

Wow!  Double wow!
In this sentence, as I read it, Lieb / Yngvason say that the entropy principle 
is independent of a physical thermodynamic system!

In other words, the entropy principle is independent of both physics and 
chemistry, yet somehow describes the behavior of physical and chemical systems. 

This infers that the entropy principle is merely the consequence of a 
particular form of mathematical function.

In other words, they are saying that the a class of monotone mathematical 
functions can be defined that is independent of thermodynamic functions. 

The message is clear. To Lieb and Yngason, a mathematical principle of entropy 
is independent of the thermodynamic principle of entropy!  

Obviously, Lieb and Yngason are merely re-arranging the ordering of concepts in 
such a way as give a coherent mathematical interpretation of a physical 
concept.  Mathematical concepts are moved from a consequence of nature to an 
antecedent of nature by invoking the concepts of "procedes" and state space.

In my view, the open question is the physical generality of this re-arranging 
of concepts.

How does one use such a conceptual re-arrangement of symbols to the predictions 
of chemical structures and living structures?

My question to you, Professor Jani, is, do any of your 150 concepts of entropy 
lead to a logico-mechanical system relevant to the pan-chemical sciences?  the 
plexus of life?

With regard to your assertion:

The nature of abstraction is one of the essential topics of CSP writings.
In your terminology, what is the mathematical or logical origin of your 
assertion that their exist a "scope of variation"? 
Perhaps you mean "scale"?  Or, perhaps you mean "index"?   Why "scope of 
variation"?
Or, do you mean that the 150 mathematical formulations of entropy is an example 
of the precision of mathematical abstraction?


Cheers
