Abstract :
It is proved that applying sucient regularity conditions to the interval matrix
[A ?? jBj;A + jBj], we can create a new unique solvability condition for the absolute value
equation Ax + Bjxj = b, since regularity of interval matrices implies unique solvability of
their corresponding absolute value equation. This condition is formulated in terms of positive
de niteness of a certain point matrix. Special case B = ??I is veri ed too as an application.
