Applications of ball spaces theory: fixed point theorems in semimetric spaces and ball convergence
Piotr Nowakowski, Filip TuroboÅ
In the paper we apply some of the results from the theory of ball spaces in the semimetric spaces. This allowed us to obtain some fixed point theorems which we believe to be unknow…

Partition function for several Ising model interface structures
Alessio Squarcini, Piotr Nowakowski, Douglas B. Abraham +1
We employ a procedure that enables us to calculate the excess free energies for a finite Ising cylinder with domain walls analytically. This procedure transparently covers all poss…
