Abstracts †

I will introduce the zooming presentation system Prezi. Blackboard in mathematics have been used traditionally, through OHP, OHC, recently we give a talk with LaTeX Beamer. On the other hand, we may not be able to ignore the superiority of using the blackboard. Prezi, which was born in Hungary is a software for using the concept of "frame" and "path", describing the idea with MindMap method. We are able to zoom in and zoom out easily, dynamic representation, is gaining attention as gradually replaces the presentation with PowerPoint. We will have an introduction about Prezi for beginners, and consider that Prezi can be a media to replace blackboard.

We first present a bit of history of TeX Live, followed by a short discussion what TeX Live is -- and what it isn't. After that we walk through a complete installation with explanations and warnings. Having set up a new installation, we use it to show the first basic steps with the TeX Live Manager (tlmgr), as well as more involved usage scenarios, both using the command line and the GUI. Finally, we will discuss the recently greatly improved support for Japanese TeX users in TeX Live, including font setup. We will close with a short list of other notable news from the latest release of TeX Live 2012.

I will give a talk about Euler Getter, a topological game. In the game, introduced by myself in 2010, two players divide the real projective plane into areas and compete on their Euler characteristics. After explaining the rule and mathematical background, I will introduce several implementations of the game.

"Region Select" is a puzzle game based on knot theory. In this talk, we explain how Region Select was created, and introduce a related game "Region Lighting" and a switch. Region Select, Region Lighting, and the switch are joint works with Akio Kawauchi and Kengo Kishimoto, and patent pending by Osaka City University.

Bicentric polygon is a polygon which has both inscribed circle and circumscribed circle. For two given circles, the necessary and sufficient condition for the existence of a bicentric triangle is known as Chapple-Euler formula. In this talk, I give another proof of this formula by using a geometrical property of Blaschke products of degree three given by Daepp, Gorkin and Mortini (2002). I also talk about an extension of this formula and related topics.
