Almost automorphic functions extend the classical concept of almost periodicity to a more flexible framework that accommodates non‐uniform recurrence in differential equations. These solutions emerge ...

Frequency domain estimation and tests of hypotheses are considered for a general multivariate distributed lag regression model. The usual vector of regression functions is replaced by a matrix of ...
