Gillat Kol: Interactive Information Theory Thursday, December 3, 2015 - 4:00pm to 5:00pm Abstract: In a profoundly influential 1948 paper, Claude Shannon introduced information theory and used it to study one-way data transmission problems over different channels, both noisy and noiseless. That paper initiated the |

Omri Weinstein: Interactive Information Complexity and Applications Monday, November 16, 2015 - 4:00pm to 5:00pm Abstract: Over the past three decades, communication complexity has been extensively used to capture the fundamental limitations in diverse areas of theoretical computer science and modern computing systems. |

Robin Kothari: Separations in Query Complexity Using Cheat Sheets Tuesday, November 17, 2015 - 4:00pm to 5:00pm Abstract: 2015 has been an exciting year for query complexity. I'll survey some of the breakthroughs made this year and then talk about some very recent work with my collaborators Scott Aaronson and Shalev Ben-David. |

Virginia Vassilevska Williams: Fine-Grained Algorithms and Complexity Tuesday, November 10, 2015 - 4:00pm to 5:00pm Abstract: |

Benjamin Rossman: The Average Sensitivity Bounded-Depth Formulas Tuesday, October 13, 2015 - 4:15pm to 5:15pm Abstract: Hastad (1986) proved an exp( n^{1/d} ) lower bound on the size of depth d+1 (unbounded fan-in) boolean *circuits* computing the PARITY function. |

Mika Göös: Communication Complexity vs. Partition Numbers Tuesday, October 6, 2015 - 4:15pm to 5:15pm ABSTRACT: |

Oded Regev: Faster algorithms for the Shortest Vector Problem Thursday, April 23, 2015 - 4:15pm to 5:15pm Abstract: We give a randomized ~2^n-time algorithm for solving the Shortest Vector Problem (SVP) on n-dimensional lattices, improving on the previous best running time of 4^n by Micciancio and Voulgaris (STOC 2010). Despite being the fastest, the algorithm is arguably also the simplest in this |

Exponential Separation of Information and Communication Tuesday, December 2, 2014 - 4:15pm to 5:15pm Abstract: In profoundly influential works, Shannon and Huffman show that if Alice wants to send a message X to Bob, it's sufficient for her to send roughly H(X) bits (in expectation), where H denotes Shannon's entropy function. |

Tilting at Windmills: The Economic Efficiency of Large Games Tuesday, November 18, 2014 - 4:15pm to 5:15pm Abstract:

3SUM is Subquadratic Tuesday, November 4, 2014 - 4:15pm to 5:15pm Abstract: The 3SUM problem is to decide, given a set of N real numbers, whether any three of them sum to zero. A simple algorithm solves 3SUM in O(N^2) time and it has long been conjectured that this is the best possible. |
