Bubbling 1/2 BPS Geometries and Penrose Limits
Yastoshi Takayama, Kentaroh Yoshida
We discuss how to take a Penrose limit in bubbling 1/2 BPS geometries at the stage of a single function z(x_1,x_2,y). By starting from the z of the AdS_5 x S^5 we can directly deri…

Open Semiclassical Strings and Long Defect Operators in AdS/dCFT Correspondence
Yoshiaki Susaki, Yastoshi Takayama, Kentaroh Yoshida
We consider defect composite operators in a defect superconformal field theory obtained by inserting an AdS_4 x S^2-brane in the AdS_5 x S^5 background. The one-loop dilatation ope…
