Integral equations and time varying linear systems.

Lucas Jódar (1986)

Stochastica

Similarity:

In this paper we study the resolution problem of an integral equation with operator valued kernel. We prove the equivalence between this equation and certain time varying linear operator system. Sufficient conditions for solving the problem and explicit expressions of the solutions are given.

A theorem on implication functions defined from triangular norms.

Didier Dubois, Henri Prade (1984)

Stochastica

Similarity:

Several transformation which enable implication functions in multivalued logics to be generated from conjunctions have been proposed in the literature. It is proved that for a rather general class of conjunctions modeled by triangular norms, the generation process is closed, thus shedding some light on the relationships between seemingly independent classes of implication functions.

On a generalization of sum form functional equation (I).

Palaniappan Kannappan (1983)

Stochastica

Similarity:

The Shannon entropy has the sum form ∑f(p) with f(x) = -x logx (x belonging to [0,1]). This together with the property of additivity leads to the 'sum' functional equation...

Construction of 0-1 matrices associated to period-doubling processes.

J. P. Lampreia, A. Rica da Silva, J. Sousa Ramos (1985)

Stochastica

Similarity:

We elaborate a method allowing the determination of 0-1 matrices corresponding to dynamics of the interval having stable, 2-periodic orbits, k belonging to N. By recurrence on the finite dimensional matrices, we establish the form of the infinite matrices (k --> ∞).
