SUMMARY:"Superconformal Mellin Amplitudes in Different Dimensions'
DESCRIPTION:Featuring Xinan Zhou\, Stony Brook University\n\nPart of the HE
	T Seminar Series.\n\nHolographic four-point functions are known for their n
	otorious computational difficulties. In the past two decades\, only a handf
	ul of them have been explicitly calculated using the standard algorithm. In
	 this talk I will introduce modern methods to compute holographic correlato
	rs efficiently\, which are inspired by the bootstrap philosophy and the on-
	shell methods of scattering amplitudes in flat space. I will show that by t
	ranslating the problem into Mellin space many difficulties encountered when
	 applying the traditional method are avoided. I will argue that imposing sy
	mmetry constraints and general consistency conditions -- avoiding all detai
	ls of the complicated effective Lagrangian -- leads to many novel results f
	or holographic four-point functions in AdS5×S5\, AdS7×S4\, AdS4×S7 and A
	dS6×_w HS4. I will conclude by outlining some interesting future direction
	s of this program.
