____

*Alexander Afriat *- /Kottler’s qualitative electromagnetism/____

*Abstract*: The hole argument, symmetries, gauge freedom, gauge fixing, 
surplus structure, topology, determinism & Cauchy-well-posedness, 
general covariance are central themes of modern philosophy of physics. 
It would be wrong to say they can all be /traced back/ to the obscure 
Kottler; but they’re all there, in some form or other—if one’s prepared 
to look hard enough. Kottler views field theories (like 
electromagnetism) as fundamentally qualitative, in other words 
‘deformable.’ The deformability and underdetermination are overcome by 
the electromagnetic constitutive relations, which give metric rigidity 
to otherwise shapeless fields, thus allowing them to propagate 
deterministically.____

*Erik Curiel* - /Semi-Classical Gravity as Effective Field Theory and 
the Information-Loss Paradox/____

*Abstract:*____

I analyze the structure and content of the Information-Loss 
Paradox, explaining what exactly the apparently problematic proposition 
is at its heart and what assumptions are required for deriving it.  I 
then discuss what bearing a resolution of the paradox could have on 
attempts to formulate a theory of quantum gravity, in light of the fact 
that the framework of semi-classical gravity, in which the paradox is 
derived, is merely an effective field theory.  I discuss two different 
ways one might treat semi-classical gravity as an effective field 
theory, and analyze the different possible consequences for each on the 
paradox.  I conclude that the paradox is not necessarily problematic, 
though for reasons quite different from those of physicists such as 
Unruh and Wald and philosophers such as Maudlin, who come to a similar 
conclusion.____

*Enrico Cinti* & *Marco Sanchioni* - /Complementar//ity Lost and 
Regained: ER=EPR vs Firewalls/____

*Abstract:*____

Hawking's black hole information paradox has been one of the most 
studied topics in the foundations of black holes. In its most modern 
form, the information paradox has evolved into the firewall paradox, 
which threatens the consistency of the description of the interior of 
the black hole given by black hole complementarity. In this talk, we 
study the conceptual foundations of the firewall paradox, and identify 
its most problematic assumption. Then, we look at how the ER=EPR 
conjecture makes a resolution of the firewall paradox possible, in the 
context of the eternal AdS black hole and its generalisations. The 
upshot of our analysis is that this resolution, however, comes at a 
price: bulk semiclassical locality is lost.____
