January 29, 2018The Institute of Reproducing Kernels is dealing with the theory of division by zero calculus and declares that the division by zero was discovered as 0/0 =1/0 = z/0 = 0 in a natural sense on 2014.2.2. The result shows a new basic idea on the universe and space since Aristoteles $($BC384 - BC322$)$ and Euclid $($BC 3 Century - $)$, and the division by zero is since Brahmagupta $($598 - 668?$)$. In particular, Brahmagupta defined as $0/0 = 0$ in Brhmasphuasiddhnta $($628$)$, however, our world history stated that his definition $0/0 = 0$ is wrong over 1300 years, but, we showed that his definition is suitable. For the details, see the references and the site: http://okmr.yamatoblog.net/

We wrote two global book manuscripts [16] with 154 pages and [17] with many figures for some general people. Their main points are:

• The division by zero and division by zero calculus are new elementary and fundamental mathematics in the undergraduate level.

• They introduce a new space since Aristoteles $($BC384 - BC322$)$ and Euclid $($BC 3 Century - $)$ with many exciting new phenomena and properties with general interest, not specialized and difficult topics. However, their properties are mysterious and very attractive.

Meanwhile, the representations of the contents are very important and delicate with delicate feelings to the division by zero with a long and mysterious history. Therefore, we hope the representations of the division by zero as follows:

• Various book publications by many native languages and with the author’s idea and feelings.

• Some publications are like arts and some comic style books with pictures.

• Some T shirts design, some pictures, monument design may be consided.

The authors above may be expected to contribute to our culture, education, common communications and enjoyments. For the people having the interest on the above projects, we will send our book sources with many figure files.

How will be our project introducing our new world since Euclid?

Of course, as mathematicians we have to publish new books on Calculus, Differential Equations and Complex Analysis, at least and soon, in order to

Our topics will be interested in over 1000 millions people over the world on the world history.
