• Please send your title and abstract to the local host at least one week before your talk.
• You title and abstract can contain simple LaTex codes for mathematics, such as
  \(\mathbb{R}\), \(\int_0^1\sin(x)d x\), and \(\displaystyle\limsup_{n\to\infty} \beta_n < \infty\). But please do not use user-defined macros.

• We would appreciate if the presentation for the SASA seminar could be tailored
  to engage a broader audience, including graduate students and faculties less
  familiar with your own field. Incorporating a comprehensive and substantial
  introductory section would be incredibly helpful and highly valued.

1. For non U.S. citizen visitors, the host needs first to fill out the following
   form: payment/reimbursement request form.
   This form will be used to determine what additional documentation may be
   needed for each visitor depending on their visa status.
