Seminar • Algorithms and Complexity • Top-Down Lower Bounds for Depth-Four Circuits

Monday, November 27, 2023 12:00 pm - 1:00 pm EST (GMT -05:00)

Please note: This seminar will take place in MC 5501 and online.

Mika Göös, Assistant Professor
Theory Group, École polytechnique fédérale de Lausanne

We present a top-down lower-bound method for depth-4 Boolean circuits. In particular, we give a new proof of the well-known result that the parity function requires depth-4 circuits of size exponential in n^{1/3}. Our proof is an application of robust sunflowers and block unpredictability.

Joint with Artur Riazanov, Anastasia Sofronova, and Dmitry Sokolov.
