An inequality for the Fourier spectrum of parity decision trees

Blais, Eric, Tan, Li-Yang, Wan, Andrew

Understand

We give a new bound on the sum of the linear Fourier coefficients of a Boolean function in terms of its parity decision tree complexity.

  • This result generalizes an inequality of O'Donnell and Servedio for regular decision trees.
  • We use this bound to obtain the first non-trivial lower bound on the parity decision tree complexity of the recursive majority function.
