> Arnold Beckmann: Consistency of equational theories and the separation 
> problem for bounded arithmetic
> 
> Abstract: The separation problem for bounded arithmetic is one of the 
> most important problems in the area due to its tight connections to the 
> question whether computational complexity classes can be separated, the 
> Millennium problem whether P equals NP or not being the most well-known 
> one.  Well studied candidates for separating theories of bounded 
> arithmetic are consistency statements of formal theories, building on 
> Kurt Goedel's famous incompleteness theorems.  The most promising 
> consistency statements are given by those of certain equational 
> theories.  In our talk, we will review the results on consistency of 
> equational theories in the context of the separation problem for bounded 
> arithmetic.  We explain the progress that has been made over recent 
> years to advance this problem, and state the research programme that has 
> resulted from it.
