Every time we go on-line to look up something or to make a purchase, we are exposing ourselves to a certain amount of risk. We risk having our identities hijacked and our private information exploited. How do we protect networks against intruders and keep information safe? We do this with cryptography. This lecture will tour the mathematical ide...

When a physical object, which is perceived as a singularity ona certain level of mathematical description, is set intomotion, a paradox may arise rendering dynamic descriptionimpossible unless the singularity is resolved by introducingnew physics in the singular core. This situation, appearing indiverse physical contexts, necessitates applicatio...

Recent presentations of Information Geometry (IG), e.g. Amari and Nagaoka (2000), consider general statistical models and general sample spaces. However, the seminal discussion by Cenkov (transl. 1982) is based on finite sample spaces, as it is in Algebraic Statistics (AS).This talk will first review basic IG from the point of view of AS. In the...
