Asymptotics of polygons in restricted geometries subject to a force von Beaton, Nicholas, Eng, Jeremy, Soteros, Christine

“… We consider self-avoiding polygons in a restricted geometry, namely an infinite L × M tube in Z3. These polygons are subjected to a force f, parallel to the …”

Formalizing the transformations of a cognitive universe von Lafaye de Micheaux, N., López, G., Vitiello, P., Beauvois, J. L.

“… This result is in accordance with experimental observations that show that every subject having an inconsistent system of beliefs (i.e., one containing contradictions) makes this system evolve towards consistency to reach a simple, consistent reference framework …”
