Question

Possible meaning to the [] in:
J is a subset of [s]

Answer 1

what's the possible meaning for the []?

Answer 2

What do you know about s?

Answer 3

s is a statistical security parameter

Answer 4

maybe it could mean indices?

Answer 5

I think I might go with that

Answer 6

Oh indices=indexes..?

Answer 7

yes
i think it could mean that

Answer 8

It took me few seconds to figure that out :D

Answer 9

Could it mean the least integer function?

Answer 10

that would mean J is a subset of just an integer

Answer 11

so i don't think that is what it means

Answer 12

let me show you what i'm looking at

Answer 13

are you interested?

Answer 14

I am!

Answer 16

page 16

Answer 17

well its on other pages

Answer 18

[s]
if we choose s=4, then [4] means...

Answer 19

I wonder if J is a subset of [4], then J is a subset of {1,2,3,4}

Answer 20

maybe [4]={1,2,3,4}

Answer 21

I was thinking the same thing too. We know for sure that for s=4, [s] has at least 2 members.

Answer 22

well J has s/2 elements
and I think J can take on any two values of that set

Answer 23

since it says |J|=2

Answer 24

thanks so much
i was getting lost alittle

Answer 25

But how come the writer didn't define what it means?!
Well, J has at s/2 elements and it's a subset of [s], and therefore [s] has to have at least s/2 elements. Right?

Answer 26

ok yes you are right

Answer 27

lol

Answer 28

Oh I found it :D

Answer 29

Read P.6.

Answer 30

Figure 3.1

Answer 31

i thought i read something about indices somewhere

Answer 32

thanks for taking your time to look and helping me

Answer 33

You're welcome!

Answer 34

I just searched [s], and it's mentioned only 8 times.

Answer 35

Are you a student?

Answer 36

Yes.

Answer 37

Are you?

Answer 38

So I guess you are going for a math degree.
Yes I'm a student.

Answer 39

Why did you assume that, because of my nickname?

Answer 40

yes

Answer 41

and also you are helping people in the math section

Answer 42

Yeah, most likely math.

Answer 43

but with those premises i made a conclusion about you

Answer 44

I can assume you're a senior or a grad math student maybe?

Answer 45

I don't want to tell you where I'm at in math
I feel like I'm totally dumb

Answer 46

Lol! You're not, but that's okay. You don't have to tell me.

Answer 47

I'm trying to get my phd

Answer 48

i got my bachelors and masters in math

Answer 49

i'm doing research in cryptography now

Answer 50

Wow, this is awesome! I'll consider myself as your student then.

Answer 51

lol

Answer 52

Can I?

Answer 53

too much pressure

Answer 54

You have a strange nickname though :P

Answer 55

Are you currently a lecturer at a college or something?

Answer 56

thats because i made it up
It was suppose to be a name for my future daughter whenever i have children

Answer 57

I teach full time at a college

Answer 58

A name of your daughter?!! I can't even read it :P

Answer 59

I haven't taught any of the upper classes. I'm scared of those

Answer 60

I hope you will have your daughter and name her whatever you want... What courses do you usually teach?

Answer 61

Cal 2, Cal 1, Trig, Algebra

Answer 62

Oh I see.

Answer 63

I might start teaching more stuff once i get my phd
I will have more time to review for those upper lever classes once the phd thing is out of the way

Answer 64

I do want to teach number theory and discrete math.

Answer 65

Yeah. In my school only those who have a PhD can give lectures. Lecturer with only a master degree can give recitations or labs maybe.

Answer 66

I'm not implying that you shouldn't give lectures, I wouldn't dare :D

Answer 67

I do give presentations but only to my advisor and his other students

Answer 68

Is that consider lecturing?

Answer 69

I don't know. And wow you want to teach number theory, this is great. You know better than I do that it's probably one of the most difficult courses in the undergrad level. Good luck!

Answer 70

I don't want to teach differential equations
I just think I'm more of an algebra person than a calculus person

Answer 71

Number theory is different than both I guess? It requires more logic and proofs than either calculus or algebra does. Course that require more logical and mathematical reasoning and proofs are the hardest to teach in my opinion.
