Hi,

There are possibly issues of interdisciplinary
work. For example Sorensen & Urzyczyn in their
Lectures on the Curry-Howard Isomorphism say that
the logic LP has no name in literature.

On the other hand Segerbergs paper, shows that
a logic LP, in his labeling JP, that stems from
accepting Peice's Law is equivalent to a logic
accepting Curry's Refutation rule,

i.e the logic JE with:

      Γ, A => B |- A
     -----------------
          Γ |- A

But the logic JE also implies that LEM was added!

Bye
