%0 Journal Article %T Stochastic Analysis Of A Two Species Model With Commensalism %A M.N.SRINIVAS %A K.SHIVA REDDY %J International Journal of Innovative Research in Science, Engineering and Technology %D 2013 %I S&S Publications %X This paper deals with an exploration on mathematical model of commensal and host species, in the presence of randomly fluctuating driving forces on the growth of the species at time ¡® ¡¯ of a conventional eco system. The model consists of a commensal ( ), a host ( ) that benefit without getting effected either positively or adversely. The model is described by a pair of non-linear differential equations. Stochastic stability, in terms of the variances of the populations of the given system is derived using technique of Fourier transform. %K Keywords:Commensal %K Stable %K Fourier transform %K host %K stochastic stability %K variance %U http://www.ijirset.com/upload/july/5_STOCHASTIC.pdf
