In 1950, Mark Graev gave a construction of two-sided invariant metrics on free groups over metrics spaces. These metrics were later used in descriptive set theory to produce exotic Polish groups. We will describe a similar construction of metrics on free products (possibly with amalgamation) of groups with two-sided invariant metrics and discuss some applications. I will try to reduce preliminaries to minimum.

Update from Old Main
I have not been very good about posting during the last month or more. So here is an update on the news in the EIU Math and CS Department.
The department welcomes a new faculty member, Ravi Somayajulu, for the fall of 2012.
The College of Science will have a new Dean, Harold Ornes. Dean Ornes will start work in the college this upcoming summer. Dean Ornes is an aquatic botanist.
Professor Andrew Mertz gave a talk on Ipad/Ipod programming on February 24 and Professor Patrick Coulton and Professor Peter Andrews spoke on invisible objects on March 2nd.
The Department will host a Geometry/Topology Day on April 7th. Research mathematicians from across the mid-west will attend. See the department webpage link on the sidebar for more information.
The 55th annual Teaching of Mathematics Conference will be held on campus April 17, 2012. See Conference web page
