June 9-13, 2025
Texas Christian University
Fort Worth, Texas

Principal speaker: Christopher Schafhauser, University of Nebraska-Lincoln

The meeting will serve to train working mathematicians and graduate students alike in recent developments and new techniques that have allowed recent progress in the classification theory for amenable \(C^*\)-algebras. In addition to the ten main lectures there will be five complementary follow-up talks by additional speakers. The program will also include other activities designed to broaden participation and to provide young researchers in the field opportunities to build professional networks and share their research.

Registration

Deadline for registration (if applying for financial support): March 31, 2025 We cannot accept further requests for financial support.
Deadline for registration (otherwise): April 30, 2025 Registration is now closed.

Registration process

We request all participants register for the conference. This consists of two steps:

  1. Follow this link to fill out a form with your information.
  2. Follow this link to pay for registration ($30), and reserve and pay for housing and meals (optional) on campus.

If your decision to attend depends on the funding received, we ask that you still complete step 1. It is fine to wait until funding decisions are communicated to then pay for registration, housing, or meals, but please be aware that we can’t reserve a room etc. until payment has been received.

The organizers will make funding decisions shortly after the March 31 deadline and contact participants with estimated funding amounts.

Registration, housing, and meal plan costs

  • The cost for housing is $93 per night. Details on accommodations are below.
  • You can choose to buy a meal plan along with your housing for an additional $30 per day. This includes breakfast, lunch, and dinner very close to the dorms. This has been a popular choice among participants of past events hosted at TCU. See below for more details.
  • Important: if you choose the meal plan for one day, you must choose the meal plan for the duration of your stay.

Use of U.S. Flag Carriers for air travel

Where applicable, the “Fly America Act” requires that NSF awardees make use of U.S. flag air carriers, even if foreign air carriers are cheaper or more convenient. You can find more information on the Fly America Act on this webpage.

Additional speakers

  • Jorge Castillejos (Institute of Mathematics, Unidad Cuernavaca at UNAM)
  • Caleb Eckhardt (Miami University)
  • Eusebio Gardella (Chalmers University of Technology and University of Gothenburg)
  • Karen Strung (Institute of Mathematics of the Czech Academy of Sciences)
  • Rufus Willett (University of Hawai’i)

Conference dinner

The conference dinner will be on Wednesday, June 11, from 6 to 8pm at Blue Mesa Grill. The address is

612 Carroll St
Fort Worth, TX 76107

Registered participants will receive information on the menu and pricing by email.

Practical

Housing

Most participants will be staying at Samuelson Hall on the TCU campus. The address is

3202 Main Drive
Fort Worth, TX 76129

Dorm rooms will be private bedrooms in suites of 2-4 persons, with one shared bathroom for 2-3 persons, or 2 bathrooms for 4 persons.

Meals; restaurant options

Breakfast, lunch, and dinner will be available at Market Square, the main dining location on campus. These are included if you purchase the meal plan, or can be bought separately (the cost will be greater, but we haven’t been told the prices yet).

Purchasing the meal plan for a night of your stay includes dinner for that night and breakfast and lunch for the following day. (So: opting for the room and meal plan from Sunday to Saturday means you get three meals every day except Sunday, where you only get dinner, and Saturday, where you only get breakfast and lunch.)

There are a number of additional dining options for lunch within walking distance of campus. Here is a short guide to some of these. They are shown in the map below.

Airports

Dallas/Fort Worth International Airport is 25 miles from TCU.

Love Field Airport is 35 miles from TCU. Shuttle, taxi and car rental services are available at the terminal.

Driving to TCU

TCU is located four miles southwest of downtown Fort Worth on University Drive. Google Maps provides the most accurate directions to campus.

From the D/FW Airport, follow the South airport exit. Take 360 South to Arlington. From 360 follow signs to I-30 West to Fort Worth. Travel through to Fort Worth (past Six Flags and the Ballpark). Travel through downtown and exit University Drive South. TCU is 2 miles from the Interstate.

From the north or south, take I-35 West to I-30 West. Travel through downtown and exit University Drive South. TCU is 2 miles from the Interstate.

From the west or east, exit I-30 to University Drive South. The campus is about 2 miles from the Interstate.

Parking

All visitors must obtain and display a visitor parking pass from the Parking & Transportation Services Department or the school or department they are visiting. Visitor passes are available 24/7 from the TCU Police Department:
