Terminology: “Currying” of a power set?

We can write a function $f:X\times Y\to Z$ as $\tilde f:X\to (Y\to Z)$. This is called “currying”. We can also write an element of a power set $Y\in \mathcal P(X)$ as $Y:X\to \{0,1\}$. It’s somewhat similar to currying. Is there a term for…

Is there a name for a logarithm with a mantissa of zero?

Not a math guy, just asking out of curiosity. I recently came to understand that a logarithm's integer and fraction parts are respectively called the characteristic and the mantissa (if that's wrong then feel free to smash me to pieces). Right now I…

How exactly does a lemma differ from another type of proposition (like a theorem or corollary)?

How exactly does a lemma differ from another type of proposition (like a theorem or corollary)? I think it is that lemmas are used to help prove theorems and coroallary are specific cases of theorems. Is this correct?

Is there a mathematical term to refer to the number of unique elements in a multiset/sequence/tuple?

Does there exist a mathematical term to refer to the number of unique elements in a multiset/sequence/tuple? For example, if a tuple $T$ is $[2, 4, 2, 10, 4, 8, 10]$, then the number of unique elements in $T$ is $4$: $$[2, 4, 8, 10].$$ The term…

Term for unintuitive equivalencies (e.g., Zorn's lemma and Axiom of Choice)?

I know there is a term for cases where two mathematical propositions are equivalent but only one is intuitive and the other (and thus the equivalence) is not. Also, the term might apply to surprising, unintuitive connections across different…

Adjective that describes a proper cumulative distribution function that may be discontinuous

If $f(x)$ is a non-atomic probability distribution function, then its integral $F(x) := \int_{-\infty}^{x}f(y)dy$ is a continuous function. However, if $f(x)$ has atoms then $F(x)$ may be discontinuous ($F$ might have jumps where $f$ has atoms).…
