The 3x+1 Periodicity Conjeture in $R$

Josefina López, Peter Stoll

The $3 x + 1$ map $T$ is defined on the $2$ -adic integers $Z_{2}$ by $T (x) = x /2$ for even $x$ and $T (x) = (3 x + 1) /2$ for odd $x$ . It is still unproved that under iteration of $T$ t…

A class of non-supersymmetric orientifolds

Anamaria Font, Jose Antonio Lopez

We study type IIB orientifolds on T^{2d}/Z_N with supersymmetry broken by the compactification. We determine tadpole cancellation conditions including anti-branes and considering d…

Strings on Eight-Orbifolds

Anamaria Font, Jose Antonio Lopez

We present several examples of T^8/P orbifolds with $P \subset S U (4)$ . We compute their Hodge numbers and consider turning on discrete torsion. We then study supersymmetric compact…
