Where do discussions about higher maths happen here on google+? Do you know of nice collections?

Research level stuff is perfectly cool. There sure must be more people sharing their arxiv finds, and closer to first hand news from their field?

And yes, I'm aware I'm looking at such a nice place right now, I'm glad to have found here, and that's why I shared "Mathematics Research" below the fold :)

I'm glad to see you like the idea, and I will, +Robert Byrne! But I also could use some help, because many things just won't turn up when I search for them. This group for example, it didn't turn up in searches and I only found it by digging into other people's "interests" tabs.

the liberation of geometry
https://www.scribd.com/doc/176494726
...so geometry was liberated from hidden intuition and many geometries were discovered, the parallel axion, the Pythagoean theorem, the rigid bodies, the Riemann's metric

+Md Ansar, how can you determine the length of the radius for each circle?

I am only assuming that from your drawing the farthest distance between the perimeter of the inner circle and the perimeter of the outer circle is 9cm. Do you understand how I formulated the outer circle area as pi•(r+4.5cm)^2?

I'm not sure where the 5cm distance stands in relation to either circles center points nor the line between those two center points - is it perpendicular? From the drawing it appears offset from a perpendicular axis and placed arbitrarily. Is it something you can use to determine the radius or circumference of the inner circle?

I have an doubt-
Suppose there is an practical exam tomorrow in a class of 99 students.The teacher in charge gives every student an chit either containing physics, bio or chemistry. each has a probability of 1/3. Now an dishonest student, who is weak in bio collects a group of 10 students and asks them to learn bio for him for some money for cheating. what is the probability that the dishonest student will pick the chit containing bio with one of the 10 students in the group he made ?

An exponential sequence has n terms. The sum of the first and second terms is p and the sum of the last two terms is q. What is the common ratio? Pls help

Does anyone want to comment or collaborate on this extension of set theory that, amongst other things, allows the non-paradoxical construction of Russell's set of all sets that do not contain themselves?

Euler God equation?
maybe because Euler started for a limit and introducing a new Abstract - Complex calculus - which can to be good but with is limit of first place definition.
At the last even Mr. Higgs will recognize his Big Boson need Inertia as Ion Murgu from Ohio, USA, defined it.

Sorry for cross posting, but here we have a bigger audience, and I do need some help with this.  
 
This is actually from a paper on knot theory, and describes a process from determining whether a graph represents a knot. But has anybody seen this process described in a graph theory context?  I am looking for a more formal definition for what they are calling a "k-circuit." It is not like any type of circuit or path I have seen in graph theory.

The paper is "Some applications of planar graphs in knot theory." Found here:

|| SANSKRIT & MATHEMATICS LECTURE ||

" For those of you that are interested in Mathematics , I thought I would share with you some of the things I found in Sanskrit literature .

All these ancient Mathematical works are so beautiful and yet there are no translations available for the public .

Only somebody who knows Sanskrit and knows Mathematics in a modern way can appreciate these works !

That is a very tiny percentage of the population .

That is just not acceptable — when there is such beauty out there and only a tiny percentage of people can appreciate that . "

I would love it if the recording of this lecture were made available. (I assume it was recorded since there is a transcript.)

Hi,

How can I find the global minimum of a function defined over high dimensional space(say 7) with least amount of computation.

Is there any formula/method which can directly give me the coordinates of points which make my function have its globally minimum value.

I need it for machine learning. Kindly help.

This is related to a possible mathematical proof, I want to know if this is doable.

Can it be proven that no mathematical object can exist outside of an axiomatic system?
That is, if the universe is an axiomatic system, and outside of it, there is no axiomatic system, could something exist or operate there?
Am I even making sense?

I believe you are right, I do assume an answer, and we can't create a non axiomatic model to proof that nothing could exist there, this wouldn't even make sense, it would be similar to creating "nothing" in order to see if it could sustain "something" in some way.
My opinion of course.

However, I can thing of few ways to proof that no object can exist outside of an axiomatic system, but indirectly.
For instance, what if it is proven that in order to exist, that which is to exist has to "be" something, that to "be something" implies having at least a "quality", which implies "description", which implies an "axiomatic system".

A 3d square exists, therefore, it's existence implies that it exists within an axiomatic structure that allow height, width, length, volume, value an so on.
Can we honestly believe that mathematics are not an intrinsic part of this universe?,
When we talk about different mathematics, are we not talking about the employment of the same mathematical structure but with different values or descriptions?.
Am I wrong to believe that there can't exist nothing without a mathematical description? And therefore, that whatever is has to be within the constraints of an axiomatic system?

What are your thoughts on this? Am I confused?

Would anyone who is conversant with the set theory NFU, like to collaborate on constructing a natural, set model of the transreal and transcomplex numbers that allow division by zero?

Hi SY L, I have started writing such a paper. I am looking for people who are well practiced with the set theory NFU to collaborate with. I don't have a target journal in mind. I plan to look for a relevant journal after the paper is written. In my experience papers go through several revisions before they find a home.

hello dear, 
I am tring to Analyse and Visualize Flows in Rivers with matlab and my data is about the flows of the river of congo i'v some problems when I run my scripts, I have a good results with the Hasen method but for the Gumbel distribution is not good, So my goals are:
1- I must be use the empirical distribution function: to build the empirical distribution function F (Fi) using the points method (Hazen).
2-secondly I need to adjust the Gumbel law: "adjust" to the empirical distribution function a Gumbel distribution F (Fi)
3- Statistical analysis of the flow of "floods" yearly for 104 years (I have the data of 104 years)
4- use now the statistical analysis plan for months debits per month over 12 months
5- finally, analysis of the temporal structure of the monthly rates of 104 years, thank you su mach for your answers
