Gorenstien Projective Precovers



We consider a right coherent and left n-perfect ring R. We prove that the class of Gorenstein projective complexes is special precovering in the category of unbounded complexes, Ch(R). As a corollary, we show that the class of Gorenstein projective modules is special precovering over such a ring.  This is joint work with Sergio Estrada and Sinem Odabasi.

We invite you to a forum discussion organized by French and Francophone Studies at UK on the Paris attacks of January 7-9, 2015. 

UK faculty from the Department of Modern and Classical Languages, Literatures, and Cultures, the Department of History, and the Department of Geography will discuss the recent deadly attacks on the French satirical magazine Charlie Hebdo and a Paris kosher market, as well as provide some context for the social and political debates that continue to emerge in the wake of the attacks.

Discussion participants:

Dr. Ihsan Bagby, Arabic and Islamic Studies, Department of Modern and Classical Languages, Literatures, and Cultures (MCLLC)



Dr. Jeffrey Peters, French and Francophone Studies (MCLLC)

Joel Pett, political cartoonist, Lexington Herald-Leader

Dr. Jeremy Popkin, Department of History

Dr. Suzanne Pucci, French and Francophone Studies (MCLLC)

Dr. Leon Sachs, French and Francophone Studies (MCLLC)

Dr. Michael Samers, Department of Geography

Dr. Sadia Zoubir-Shaw, French and Francophone Studies (MCLLC)

Mexico is in a historic moment right now in which change appears to be in the hands of citizens who are demanding an end to the corrupt governance that has resulted in decades of human rights abuses. This lecture will explore violence and activism in Juárez, Mexico focusing on how activists and human rights defenders work to counter a state controlled media monopoly that blames victims for their own deaths.

Bio: Alice Driver is the author of "More or Less Dead: Feminicide, Haunting, and the Ethics of Representation in Mexico" (University of Arizona Press 2015). She recently translated "Abecedario de Juárez," a collaboration between journalist Julián Cardona and artist Alice Leora Briggs that explores and maps the new language of violence in Mexico. 

A single sheet of sp^2-hybridized carbon atoms, called Graphene, is presently one of the most widely studied materials in the scientific community. Following a bried introduction of Graphene and its unique properties, I will present evidence for the amplification of surface plasmon coupled emission (SPCE) from Graphene-Ag hybrid films. SPCE is a novel analytical technique in which the isotropic emission of a fluorophore is combined with the surface plasma resonance of a Ag (or Au) think film to yield highly directional emission from the so-called plasmaphore, and thus greatly increased sensitivity. In another project, we harnessed the nonlinear optical properties of Graphene in conjunction with those of C_60 to fabricate an all-optical analog of a diode. Our all-carbon optical diode, built from a Graphene and C_60 sandwiched structure, is passive, polarization independent and most importantly has no phase-matching constraints. Evidence for tunable nonreciprocity factor and potentially large bandwidth capability with be presented. This work was done in collaboration with team members from Clemson University, USA (M. Karakaya, R. Podila, K. Lingam), Sri Sathya Sai Institute of Higher Learning, India (P. Mulpur, B. Anand, R. S. Satish) and Raman Research Institute, India (R. Philip).
