• Penrose limit and pp-wave background
• AdS-CFT Correspondence
• Super-strings and Heterotic Strings

We find a new Penrose limit of AdS(5) x S-5 giving the maximally supersymmetric pp-wave background with two explicit space-like isometries. This is an important missing piece in studying the AdS/CFT correspondence in certain subsectors. In particular whereas the Penrose limit giving one space-like isometry is useful for the SU(2) sector of N = 4 SYM, this new Penrose limit is instead useful for studying the SU(2 vertical bar 3) and SU(1, 2 vertical bar 3) sectors. In addition to the new Penrose limit of AdS(5) x S-5 we also find a new Penrose limit of AdS(4) x CP3.
