On Sunday, November 23, at 6:00 pm, the CC2 Hall Government is having a “Thanksgiving Dinner.” The Hall Government officers, the RAs and a few peer mentors are collaborating on making dishes for everyone to enjoy. To come to this dinner, they are requesting that you bring a non-perishable food item to donate to Big Blue Pantry. This will be one of the philanthropy events for CCII this semester and will count as a Wired event!!
Dr. Harsh Mathur Case Western Reserve University The imprint of primordial gravitational radiation on the cosmic microwave background polarization, if observed, is considered smoking gun proof of inflation. I will discuss how such an observation can not only provide information about the Universe in the epoch of inflation but also constrain theories of grand unification. In the second part of the talk I will discuss tests of gravity on scales ranging from the tabletop to the cosmological scale. Such tests may shed light on physics beyond the standard model.
Recent research by faculty and students in the Office for Policy Studies on Violence Against Women sheds light on the impact sexual assault can have on student performance.
Professor Pradyumna (Paul) Karan of the Department of Geography reflects on the the fifty year project of internationalizing the University of Kentucky.
Gismo Therapeutics Inc., a New York-based biotech startup, has recently relocated its company to the University of Kentucky Advanced Science and Technology Commercialization Center, a business incubator housing new and emerging technology-based companies on UK’s campus.
The Center for English as a Second Language is pleased to welcome 53 students from Mexico. The students arrived over the weekend of November 9th and will be visiting scholars for one month.
Title: Conditions for the toric homogenous Markov Chain models to have square-free quadratic Groebner basis
Abstract: Discrete time Markov chains are often used in statistical models to fit the observed data from a random physical process. Sometimes, in order to simplify the model, it is convenient to consider time-homogeneous Markov chains, where the transition probabilities do not depend on the time. While under the time-homogeneous Markov chain model it is assumed that the row sums of the transition probabilities are equal to one, under the the toric homogeneous Markov chain (THMC) model the parameters are free and the row sums of the transition probabilities are not restricted.
In this talk we consider a Markov basis and a Groebner basis for the toric ideal associate with the design matrix (configuration) defined by THMC model with the state space with $m$ states where $m \geq 2$ and we study when THMC with $m$ states have a square-free quadratic Groebner basis. One such example is the embedded discrete Markov chain for the Kimura three parameter model. This is joint work with Abraham Martin del Campo and Akimichi Takemura.
Departmental Tea hosted by the Gradaute Student Council. All are welcome to come and mingle over coffee, tea, and cookies!
Title: An introduction to operads
Abstract: Operads first arose in the 60's and 70's for the study of loop spaces, but there was a large resurgence of interest in the 90's once connections with Koszul duality, moduli spaces, and representation theory were realized. I will discuss the definition and familiar examples in both topology and algebra. We will see Stasheff polyhedra in the context of loop spaces as well as examples related to moduli spaces.
