They aren't part of the Greek standard, and aren't used in various
Greek code page implementations, but they *do* appear in English
publications as presentation forms of other Greek letters. Their
use as mathematical symbols is generally undistinguishable from the
use of other Greek letters (alpha, gamma, chi...) as mathematical symbols.
The upsilon hook versions, in particular, are clearly just variant
forms of upsilon.
