Course Objectives: Walking through Kemeny Hall, you will hear professors and students discussing a myriad of topics.

The slope of a line is most commonly quoted as the "rise over the run." More precisely, this means the $\Delta y$ over $\Delta x$, or $m=\Delta y/\Delta x$, where $m$ is commonly assigned to be the "slope." Now, do you remember how the slope works? Does a vertical line have an infinite slope or a zero slope? What about... | CommonCrawl |
We study the blow-up of $H$-perimeter minimizing sets in the Heisenberg group $\mathbb H^n$, $n\geq 2$. We show that the Lipschitz approximations rescaled by the square root of excess converge to a limit function. Assuming a stronger notion of local minimality, we prove that this limit function is harmonic for the Kohn... | CommonCrawl |

$t_i$, as well as through every stall along the pat... | CommonCrawl |

Abstract: Nakada's $\alpha$-expansions interpolate between three classical continued fractions: regular (obtained at $\alpha=1$), Hurwitz singular (obtained at $\alpha$=little golden mean), and nearest integer (obtained at $\alpha$=1/2). This talk will consider $\alpha... | CommonCrawl |
Abstract: A simplified Gyunaydin–Gyursey model, in which a Majorana field constructed using quaternions combines a lepton and a color quark, is considered. Formulation of the gauge principle directly in the quaternions leads to the appearance of two vector quaternion gauge fields, these corresponding to the decompositi... | CommonCrawl |
