Colloquium 12/1: Kate Kochalski on Fluid Limit for a Batched Processor Sharing Queue

Kate Kochalski of the University of Virginia will speak as part of the R. W. Yeagy Colloquium series on Friday, December 2 at 2pm in Math Building 357.

Abstract: We consider a sequence of single server queues operating under a service policy that incorporates batches into processor sharing. There are measure-valued processes that describe each system in the sequence. Motivated by the law of large numbers from classical probability, we find a fluid limit of these processes.  This is a limiting stochastic process that is easier to work with than the original stochastic processes.  We can then use this simpler limiting object to approximate what happens in the system. In particular, we show the model is completely described by its initial state and each new batch will start in a predictable, periodic way.

About Us

The Department of Mathematics and Statistics is a friendly and supportive place for our students. Our faculty are committed to excellence and continual improvement in teaching and advising students through our challenging curriculum:

Our math clubs are very active in hosting math talks and participating in conferences, fundraisers, and social activities.

We offer one of the leading certification programs in the state in mathematics teaching. The department proudly produces qualified teachers at all levels.

We offer dual-credit coures to local and rural schools and make visits to speak about mathematics and statistics.

Why study mathematics?

Mathematics is perhaps the most intellectually challenging and practical major you can choose. Some major in math for the enjoyment and beauty of the subject. Others major in math for its practicality and applicability to the sciences, engineering, finance, and even the social sciences. Mathematics develops rigorous analytical thinking skills that are prized in all fields of human endeavor.

Mission Statement

The purpose of the Department of Mathematics and Statistics is to attract and retain the best available scholars who actively pursue knowledge of mathematics, statistics, and/or mathematics education and who skillfully communicate their knowledge of the subject to their students, colleagues, and the community as a whole.

Specific roles of the Department are:

  1. To provide a sound curriculum for students who wish to pursue a career in mathematics or statistics in business and industry;
  2. To provide service courses for students who are majoring in some other department, but who need mathematics or statistics as a tool or to satisfy general degree requirements;
  3. To offer preparation to those who are planning to pursue a graduate degree;
  4. To prepare teachers for positions in colleges, universities, and public or private schools.
