چکیده

The discrete Lotka–Volterra equation over p-adic space was constructed since p-adic space is a prototype of spaces with non-Archimedean valuations and the space given by taking the ultra-discrete limit studied in soliton theory should be regarded as a space with the non-Archimedean valuations given in my previous paper (Matsutani S 2001 Int. J. Math. Math. Sci.). In this paper, using the natural projection from a p-adic integer to a ring Z/pZ, a soliton equation is defined over the ring. Numerical computations show that it behaves regularly. PACS numbers: 05.45.Yv, 02.40.−k, 02.40.Re, 02.60.−x, 05.50.+q

The matrix realization of affine Jacobi varieties and the extended Lotka-Volterra lattice

Abstract: We study the representative for the gauge equivalence class MF related to certain types of N by N monodromy matrices whose entries are polynomials of a spectral parameter z. Let X be the algebraic curve given by the common characteristic equation for MF . Then the representative corresponds to the matrix realization of the affine Jacobi variety of X . When we relate MF to the Lax matr...

Stochastic delay Lotka–Volterra model

We reveal in this paper that the environmental noise will not only suppress a potential population explosion in the stochastic delay Lotka–Volterra model but will also make the solutions to be stochastically ultimately bounded. To reveal these interesting facts, we stochastically perturb the delay Lotka–Volterra model ẋ(t) = diag(x1(t), . . . , xn(t))[b + Ax(t − τ)] into the Itô form dx(t)= dia...

Permanency and Asymptotic Behavior of The Generalized Lotka-Volterra Food Chain System

In the present paper a generalized Lotka-Volterra food chain system has been studied and also its dynamic behavior such as locally asymptotic stability has been analyzed in case of existing interspecies competition. Furthermore, it has been shown that the said system is permanent (in the sense of boundedness and uniformly persistent). Finally, it is proved that the nontrivial equilibrium point...

Classifying Finite 2-nilpotent P-groups, Lie Algebras and Graphs: Equivalent Wild Problems

We reduce the graph isomorphism problem to 2-nilpotent p-groups isomorphism problem (and to finite 2-nilpotent Lie algebras the ring Z/pZ. Furthermore, we show that classifying problems in categories graphs, finite 2-nilpotent p-groups, and 2-nilpotent Lie algebras over Z/pZ are polynomially equivalent and wild.
