style="padding:0px;"> The 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 Aristotele (BC384 - BC322) and Euclid (BC 3 Century - ), and the division by zero is since Brahmagupta (598 - 668 ?).</div><div style="padding:0px;"> </div><div style="padding:0px;"> </div><div style="padding:0px;">However, note that the division by zero $1/0=0$ having a mysterious long history was, in fact, known as the generalized Moore-Penrose solution of the fundamental equation: $ax=b$.</div><div style="padding:0px;"> </div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">The division by zero calculus is a new and fundamental concept, and it may be defined simply as follows:</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">For a function $y = f(x)$ which is $n$ order differentiable at $x =a$, we will {\bf define} the value</div><div style="padding:0px;">of the function, for $n \ge 0$</div><div style="padding:0px;">$$</div><div style="padding:0px;">\frac{f(x)}{(x -a)^n}</div><div style="padding:0px;">$$</div><div style="padding:0px;">at the point $x=a$ by the value</div><div style="padding:0px;">$$</div><div style="padding:0px;">\frac{f^{(n)}(a)}{n!}.</div><div style="padding:0px;">$$</div><div style="padding:0px;">For the important case of $n=1$,</div><div style="padding:0px;">$$</div><div style="padding:0px;">\frac{f(x)}{x -a} |_{x=a} = f^\prime(a).</div><div style="padding:0px;">$$</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">Look the simple evidence of its importance:</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;"> </div><div style="padding:0px;"> viXra:2010.0228 submitted on 2020-10-28 21:39:06,</div><div style="padding:0px;">Division by Zero Calculus and Euclidean Geometry - Revolution in Euclidean Geometry</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">Look a simple video talk for its essence at some international conference:</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">https://media.cmd.gunma-u.ac.jp/media/Play/ef7ca967c3fd4dabb188128fd6038cb81d</div><div style="padding:0px;"> </div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">For the detailed information, the book will be published soon as:</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">S.

The topics may be identified as the division by zero calculus. However, the contents will be related to our serious problems:</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">What is ZERO?</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;"> </div><div style="padding:0px;">What is Division by Zero, in some serious sense?</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">The problems may be related to mathematical philosophy, long history and our culture.</div><div style="padding:0px;">The starting of the International Journal will not be still easy at this moment, however, for its importance, we would like to manage to found the new Journal in some near future. So, we will need the kind help of the leading mathematical scientists.</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">How will be the related physicists?</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">Computer scientists?</div><div style="padding:0px;">\medskip</div><div style="padding:0px;"> </div><div style="padding:0px;">We attached the journal style (in a rough way) in the below.

The journals suggested by you are very interesting and new to the subject area. We accept to publish both journals under your editorship. We need following things from your side for preparing the sample web page of the journals.</div><div style="padding:0px;"> </div><div style="padding:0px;">1. Aim and Scope , Instructions to Authors, List of the editorial board members, Frequency of the journal.</div><div style="padding:0px;"> </div><div style="padding:0px;">Of course, they are important. However, for Frequency of the journal, we should consider it in a new type. We should not loss our valuable time for us and for the authors. We all do not like to loss our time for publication and refereeing time. This will mean that we should not fix Frequency of the journal. When a paper was accepted officially, then, soon the paper should be presented on line. So, some time, we can give the number for an accepted paper. If you wish to publish the papers in some Journal style or book, you will be able to publish them in some papers with a suitable page numbers. How will be this idea?</div><div style="padding:0px;"> </div><div style="padding:0px;">2. The journal will be free for the readers (open Access publications). The journal will not charge any fee from the authors for getting published in the journal.</div><div style="padding:0px;">Fine: However is it possible?</div><div style="padding:0px;"> </div><div style="padding:0px;">3. We need some sample images from your end to prepare the cover page for the journals.</div><div style="padding:0px;">We can consider them with computer graphics.</div><div style="padding:0px;">For a paper style, how will be it in a free style, we request it PDF in order not to</div><div style="padding:0px;">loss any valuable time for us and for the authors.</div><div style="padding:0px;"> </div><div style="padding:0px;">I think: this is an ideal style</div><div style="padding:0px;"> </div><div style="padding:0px;">viXra:2010.0228 submitted on 2020-10-28 21:39:06,</div><div style="padding:0px;">Division by Zero Calculus and Euclidean Geometry - Revolution in Euclidean Geometry</div><div style="padding:0px;"> </div><div style="padding:0px;">The problem is no refereeing procedures.
