Using basic linear algebra as a natural language of special relativity, and assuming very little knowledge of physics, we present a novel linear-algebraic derivation of the Lorentz transformation. Through the geometry of Minkowski diagrams, we analyze properties and paradoxes of special relativity including the Twin paradox and the bug-rivet paradox.Dr. de Pillis is a renowned cartoonist and animator, and his new book entitled Illustrated Special Relativity Through its Paradoxes is a fusion of Linear Algebra, Graphics, and Reality.

Emory University, Georgia Tech and Georgia State University, with support from the
National Science Foundation and the National Security Agency, will continue the
series of mini-conferences and host a series of 9 new mini-conferences from
2013-2016. The 11th of these mini-conferences will be held at
Georgia State University from January 25-26, 2014. The conferences will stress a variety of
areas and feature one prominent researcher giving 2 fifty minute lectures and 4
outstanding researchers each giving one fifty minute lecture. There will also be
several 25 minute lecturers by younger researchers or graduate students.

I introduce a class of dynamical systems which exhibit motion in their
lowest-energy states and thus spontaneously break time-translation
symmetry. Their Lagrangians have nonstandard kinetic terms and their
Hamiltonians are multivalued functions of momentum, yet they are perfectly
consistent and amenable to quantization. Possible applications to
condensed matter systems and cosmology will be discussed.

Equilibrium computation is among the most significant
additions to the theory of algorithms and computational complexity in
the last decade - it has its own character, quite distinct from the
computability of optimization problems.
Our contribution to this evolving theory can be summarized in the
following sentence: Natural equilibrium computation problems tend to
exhibit striking dichotomies. The dichotomy for Nash equilibrium,
showing a qualitative difference between 2-Nash and k- Nash for k > 2,
has been known for some time. We establish a dichotomy for market
equilibrium.
For this purpose. we need to define the notion of Leontief-free
functions which help capture the joint utility of a bundle of goods that
are substitutes, e.g., bread and bagels. We note that when goods are
complements, e.g., bread and butter, the classical Leontief function
does a splendid job. Surprisingly enough, for the former case, utility
functions had been defined only for special cases in economics, e.g.,
CES utility function.
We were led to our notion from the high vantage point provided by an
algorithmic approach to market equilibria.
Note: Joint work with Jugal Garg and Ruta Mehta.
