The meaning of my art signature is my first name in alternative symbols. The short form of my real name is Lena, and
L∃N∀ is my signature art seal. ∃∀ - are math signs, which mean "exists"
∃ and "for all"
When I started using my signature online in 2000s, there was no safe-to-use Unicode character with a line above (logical "not") for the sign
∀, "for all" - and thus the meaning changed from "exists not for all" to almost the opposite "exists for all", which I find amusing - hope you do too!
My last name, Nechet, means "odd number" in Ukrainian, like
-1, 1, 3, 5, 7, ... - integers that cannot be divided by 2 exactly. This is my birth name.
