Original abstract

This paper deals with asymptotic properties of a vector difference equation with delayed argument $$ \Delta x_k=Ax_k+Bx_{\lfloor\lambda k\rfloor},\qquad 0<\lambda<1,\quad k=0,1,2,\dots, $$ where $A,B$ are constant matrices and the term $\lfloor\lambda k\rfloor$ is the integer part of $\lambda k$. Our aim is to emphasize some resemblances between the asymptotic behaviour of this delay difference equation and its continuous counterpart.

Czech abstract

Článek se zabývá asymptotickým vlastnostem vektorové diferenční rovnice se zpožděným argumentem $$ \Delta x_k=Ax_k+Bx_{\lfloor\lambda k\rfloor},\qquad 0<\lambda<1,\quad k=0,1,2,\dots, $$ kde $A,B$ jsou konstantní matice a výraz $\lfloor\lambda k\rfloor$ označuje celočíselnou část $\lambda k$. Naší snahou je poukázat na některé podobnosti asymptotického chování řešení této zpožděné diferenční rovnice a asymptotického chování řešení její spojité analogie.
