[EN] The main goal of this work is to show what happens when instead
of the logistic map with a scalar we use a matrix. This work is based on
a paper of 2011 from a investigation team of Lithuania[1]. The logistic
map is a polynomial mapping (equivalently, recurrence relation) of de-
gree 2, often cited as an archetypal example of how complex, chaotic
behaviour can arise from very simple non-linear dynamical equations.
The map was popularized in a seminal 1976 paper by the biologist
Robert May, in part as a discrete-time demographic model analogous
to the logistic equation rst created by Pierre Fran cois Verhulst.
The logistic map is one of the most simple forms of a chaotic process.
Basically, this map, like any one-dimensional map, is a rule for getting a
number from a number. The parameter a is xed, but if one studies the
dynamics of the the map for di erent values of a, it is found that this
parameter is the catalyst to show a variety of possibilities (including
chaos).
Dynamical properties of the iterative map are explored in detail
when the order of matrices is 2. We will see that the evolution of the
logistic map depends not only on the control parameter but also on
the eigenvalues of the matrix of initial conditions. The second part
is reserved for computational examples that are used to demonstrate
the convergence to periodic attractors and the sensitivity of chaotic
processes to initials conditions.
In the rst chapter we are going to do a short introduction about the
well-known logistic map with a scalar variable and a several properties
of square matrices of order 2. We will see the algebraic representation
of matrices and some properties of the matrix with a few corollaries.
The second chapter will include the dynamic of the logistic map with
matrices and parametric expressions of idempotent and nilpotent ma-
trix. The second part of this chapter will contain theorems and results
about the dynamics of the logistic map of matrices, such as the theo-
rem of bounded four iterated sequences in the case of idempotents and
nilpotent matrices.
In the third chapter we illustrate the behavior of iterated matri-
ces of order 2 with some computational experiments. We will to see
how the nilpotent and idempotent matrix react by changing the initial
conditions and the parameter a and the attractors in every case are
the key point for beginning the study of these experiments. The last
part of the third chapter will be the concluding remarks like advan-
tages, disadvantages and a short comparator with the scalar form of
the iterative logistic map.
