  "textContent": "“The next TCS+ talk will take place this coming Wednesday, March 18th at 1:00 PM Eastern Time (10:00 AM Pacific Time, 18:00 Central European Time, 17:00 UTC). **Chris Gartland** from UNC Charlotte will speak about “” _-Distortion of EMD over Grids_ “” (abstract below).\n\nYou can reserve a spot as an individual or a group to join us live by signing up on the online form. Registration is _not_ required to attend the interactive talk, and the link will be posted on the website the day prior to the talk; however, by registering in the form, you will receive a reminder, along with the link. (The recorded talk will also be posted on our website afterwards) As usual, for more information about the TCS+ online seminar series and the upcoming talks, or to suggest a possible topic or speaker, please see the website.\n\n> Abstract: The Earth Mover Distance (EMD) is a popular metric used in the comparison of probability distributions over a metric space, and low-distortion embeddings of this metric into  is a commonly used approximation tool. We will discuss a general technique of using Sobolev-type inequalities to prove lower bounds for the -distortion of EMD. While the main focus will be on describing the specific Sobolev-type inequality for the planar grid , we will also mention results for the higher dimensional grids , . Based on joint work with Mikhail Ostrovskii, Yuval Rabani, and Robert Young.\n\n“\n\nBy plustcs",
