C harting the landscape ofsupercriticalstring theory

Specialsolutionsofstringtheory in supercriticaldim ensionscan interpolatein tim ebetween theories with dierent numbers ofspacetim e dim ensions (via dim ension quenching) and dierent am ounts ofworldsheet supersym m etry (via c-duality). These solutions connect supercriticalstring theoriesto the m ore fam iliarstring duality web in ten dim ensions,and provideapreciselinkbetween supersym m etricandpurelybosonicstringtheories.Dim ension quenching and c-duality appearto benaturalconceptsin string theory,giving riseto large networksofinterconnected theories.W edescribesom eofthesenetworksindetailanddiscuss generalconsistency constraintson thetypesoftransitionsthatarisein thisfram ework.
