DESCRIPTION:TITLE: Essential Covers of the Cube by Hyperplanes\n\nSpeaker:
 \n Igor Araujo\n\nAffiliation:\n University of Illinois Urbana-Champaign\n
 \nLocation:\n contact Sabrina Lato for Zoom link\n\nABSTRACT:  An essenti
 al cover of the vertices of the n-cube\n$\\{0\,1\\}^n$ by hyperplanes is a
  minimal covering where no hyperplane\nis redundant\, and every variable a
 ppears in the equation of at least\none hyperplane. Linial and Radhakrishn
 an gave a construction of an\nessential cover with $\\lceil \\frac{n}{2} \
 \rceil + 1$ hyperplanes and\nshowed that $\\Omega(\\sqrt{n})$ hyperplanes 
 are required.
