## The Stochastic Group

I found your discussion of why you chose this article interesting. You start out sounding like you are going to answer the question “should we study this group?” but you don’t take a stand on the issue in your conclusion. My stance on the issue after reading your review? That it would be a good topic for an exploratory problem or homework problem. Once students know about Special and General Linear Groups, they can generalise the ideas to Stochastic groups and apply the methods they learned to a new situation. It’s always good to have more examples, so I’m glad you told us a bit about this group.

I’m curious why it’s called the Stochastic Group? Do you know? I assume that each column adding up to 1 has something to do with probability, but I’ve never come across this before.

Dear All,

I am interested to the topic of stochatic phenomenon especially in order to explore the corrosion mechanism in nano stuctures to support my research group (at my Dept of Physics, Sepuluh Nopomber Institute of Technologi (ITS) Surabaya, Indonesia) in developing Nano Technology at my country.

You know one of stochastic model that has been commonly used for the purpose is in the following nonlinear first order differential equation driven by white noise.

dy/dt+py=Qy^3 + Acos(2Пft)+δ(t-t’)

where δ(t-t’) is white noise mentioned. Of course imposible to obtain analytic solution of the above model. But I believe analytic solution of Ordinary part of the DE will help in creating accurate solution of the stochastic model.

Recently I have been developing a new method so-called SMT (stable modulation technique) for solving first order ordinary differential equation (ODE) based applying a new modulation scheme that I introduced as stable modulation in which solution of linear solution part of the ODE is substituted into amplitude of the nonlinear solution part. Here, solution of the nonlinear part must be written in a modulation function AF(A) that it’s amplitude A also including at the phase function. A. The SMT succesfully in solving the general Bernoulli Differential Equation (BDE) dy/dx+p(x)y=Q(x)y^n, where n±1 oor another ODE that can be transformed into the BDE. As I inform in this forum previously, the utilize of SMT has been posting at http://eqworld.ipmnet.ru/forum/viewtopic.php?f=2&t=34&start=20.

Now, I invite you to collaborate with me especially to develop the SMT for solving the general of inhomogenous of BDE dy/dx+p(x)y=Q(x)y^n + f(x), where f(x) is arbitrary force function.

Okay, I wait you all who are interested to my purpose. You contact me via email at aliyunus@rohedi.com, or by leaving some comments at my website http://rohedi.com and/or at my wordpress http://rohedi.wordpress.com.

Thank you very much for your attention.

My best Regards,

Rohedi.

Hi,

I read at

http://eqworld.ipmnet.ru/forum/viewtopic.php?f=2&t=34&start=30

there is an apportunity to collaborate in developing the SMT to solve the key mathematics model of developing Nano Technology,

dy/dx+p(x)y=Q(x)y^n + f(x) , n≠1

Please visit to the above address.

On the blog math I also post some related ordinary differential equation that commonly become an ordinary part of stochastic differential equation. For instance, the following form

dy/dt=p(t)y^2+q(t)y+r(t)+δ(t-t’),

where dy/dt=p(t)y^2+q(t)y+r(t) called as the general Ricatti differential equation. Do you know how to create the exact solution of the Ricatti’s DE?.

Thx.
