A
function
is locally integrable when its
absolute value
has finite
integral
over every compact
subset
of its domain. It
defines
a
regular
distribution
by integration against
test functions
.

** is
a
function
defined on
a
measurable space
(often \(\mathbb{
R
}^
n
\) or
a
subset
thereof) that is integrable within every compact
subset
