A measurable, in general complex-valued, function $ K (x, s) $
satisfying the conditions: 1) $ \overline{ {K (x, s) }}\; = K (s, x) $
almost-everywhere on $ E \times E $,
where $ E $
is a Lebesgue-measurable set of points in a finite-dimensional Euclidean space; and 2) $ \int _ {E} | K (x, s) | ^ {2} ds < \infty $
for almost-all $ x \in E $.
