Arithmetic Spacetime Geometry from String Theory

An arithmetic framework to string compactification is described. The approach is exemplified by formulating a strategy that allows to construct geometric compactifications from exactly solvable theories at $c=3$. It is shown that the conformal field theoretic characters can be derived from the geometry of spacetime, and that the geometry is uniquely determined by the two-dimensional field theory on the world sheet. The modular forms that appear in these constructions admit complex multiplication, and allow an interpretation as generalized McKay-Thompson series associated to the Mathieu and Conway groups. This leads to a string motivated notion of arithmetic moonshine.Comment: 36 page

Radikalisme Agama Legitimasi Tafsir Kekerasan di Ruang Publik

Religious radicalism shows a high intensity over the last decade in Indonesia. This religious radicalism subsequently brings a massive impact when it is admitted by the action of choosing violence as the only way. In this article, we put forward our arguments: first, the point of intersection between violence and religion; second, radicalism used as a method to respond to various issues such as injustice, and so on. Third, regarding alternative methods that can be done in order to minimize radical action and understanding in Indonesia. This paper confirms three main points. First, the teaching of religion, especially Islam basically contains the peace teachings and safety; therefore, one was very anti-violence and radical actions. Second, radical action can be a method to hear our voices in response to various injustices that occur in a few places in the world. Third, understand the narrowly religious texts have an impact on building understanding and narrow action anyway. &nbsp
