i figured it out, the elements that can be GLB in (f,g) are e and b. Since you cannnot determine whether e is greater than b or b is greater than e due to the lack of relationship between e and b, there is no GLB. The same logic applies to determine the GLB and LUB of other pair of elements.

FYI, you don't call the symbol for the empty set "phi". Phi is a greek letter that looks a little similar to the symbol for the empty set, but mathematicians are not using the greek letter phi in this case, it is just it's own symbol that denotes the empty set.

GLB(f,g) for all pair isn't defined, thus the set is empty. since the two preceding lower bounds are incomparable, we can't define greatest lower bound.
Lower bound of (f,g) - abce Let's check for GLB : a - All elements of LB related to a ? No [Using Hasse Diagram] b - All elements of LB related to b ? No [Using Hasse Diagram] c - All elements of LB related to c ? Obviously No [Using Hasse Diagram] e - All elements of LB related to e ? Obviously No [Using Hasse Diagram] So, GLB = Phi
all videos are arranged so well in a proper sequence
Fantastic videos. These videos are alone going to help me pass maths this semester.
Thank you so much. Your one lecture clears all my doubts about the lattice topic
wouldn't b GLB(f,g) = e?
Yes true..
@@adityanprakash1281 not at all
Same doubt

@@barlog6679 thank you for pointing out my same question and also for giving the answer of it. That is something that i didn't know.
You are a life saviour sir🔥💯💥
Please list the related playlist in the video description as well, it makes it much easier to navigate.
Well explained,with more examples,there is no doubt n understand
this guy is an amazing teacher omg
6:12, example 2 (a), what is the GLB and LUB of pair (d and g)?
GLB d and LUB g
@@enes5345
couldn't be like this?
GLB is f
LUB is ø
how GLB is d when they first meet in f?
@@marah8158
Glb cant be F because in glb we go neeche and for F hum upar jaare h d se toh F toh nhi h but hn it makes sense glb would be d and lup be d.
For(d, g)
LB(d, g) =d
GLB(d, g) =d
UB(d, g) =g
LUB(d, g) =g
Hello, at 7:25 can we say that the lower bounds of (f,g) are b,e,c,a but since b and e are not comparable -> No upper bound ?
yes
Upper bound of (f,g) is h. There is no lower bound for (f,g). You should have written "No Lower Bound".
@@rajeshprajapati6662hey y e can't be considered as GLB?
Please could you explain...
No bro

Yeah that was surprising for such a well-presented and informative video to make this error

Thank you❤❤ neso academy, I grateful to for my sessional exams
Hi five bro 🤜
Thankyou sir you rescued me a day before exam 😊😅
Thank u so much sir.....all videos are in proper sequences
sir your voice so soothing ..after hearing that it makes maths a very easy subject. thank u for ur hardwork.
From figure (a)
Consider the incomparable pair (d,g)
GLB(d,g)=f
LUB(d,g)=¢( null set)
So, this is not lattice.
I have doubt .. please clarify that.
Lub of d and g is g
same bro
i guess it is not a lattice
This is somewhere excellence is found!
8:45 example 3 was the same as in my notebook
at 8:15 in example(c) why didn't you consider (b,c) as incomparable????
You can consider it and you will find that unrelated pair (b,c) has GLB = a and LUB = g.
This video is absolutely amazing!
thanks a lot sir..Your videos are so easy to understand and organised...
Thank you, it was easy to understand and you set the previous knowledge requirements from the start.
GLB(f,g) for all pair isn't defined, thus the set is empty. since the two preceding lower bounds are incomparable, we can't define greatest lower bound.
bhai tu IIT ka hai?
Loved the explanation, you helped me a lot. Thx!
Very well explanation Sir !!
fantastic explanation
thanks man,apppreciate your work
sir in example (b) isnt GLB of f and g is a? By following the path downwards we can find a lowerbound
Lower bound of (f,g) - abce
Let's check for GLB :
a - All elements of LB related to a ? No [Using Hasse Diagram]
b - All elements of LB related to b ? No [Using Hasse Diagram]
c - All elements of LB related to c ? Obviously No [Using Hasse Diagram]
e - All elements of LB related to e ? Obviously No [Using Hasse Diagram]
So, GLB = Phi
thanks man!@@rajeshprajapati6662
i will pass because of you. god bless you!
It’s really helpful
At 6:17 why don't we consider (g, d) to check either they have glb and lup
because d is related to g through transitive property
Excellent method..❤
Thank you
Please add python and Dynamic programming courses too
Nice explanation
Way better than nptel
Amazing !🎉🎉🎉🎉
In fig (c) why don't you consider f,e and d,c as incomparable pairs ?
{1,2} lub is null then how it is a lattice
Thanks so much
Good morning every one
You're a legend
Very helpfull
nice expalined properly
i just curios when identifying part c, why we didn't consider (b,c) only (f,g) and (d,e)?
great video sir
what does the "rank" of a lattice mean? what's a "rank-1" lattice?
thank u so muchhhh very helpfullll!!!!!!!
please start providing the pdfs
Sir ji direct product of lattice explain videos
Can someone please explain what do we mean by 'incomparable elements '.
It means if neither aRb nor bRa..
Lb(f,g)=b,e,c,a b notrelates to e. So phi
Doesn't 3 also divide 12?
Thku
Wow 😲
b,c ???
