Tautological bundle Puns

My goal is to integrate the first Chern class of the tautological line bundle. To this end I calculated the connection matrix for the connection obtained by projecting the canonical flat connection of C^2 onto the line bundle and using the frame e([1:z]) = e_1 + z e_2, where {e_1, e_2} is the canonical basis of C^2 . This yields for the only element of the connection matrix the 1-form w = z*/(1+|z|^2 ) dz, with z* the complex conjugate of z. This is still in accordance with exercise 18, page 24 of http://www.staff.science.uu.nl/~crain101/DG-2015/main10.pdf

Now to compute the curvature matrix I wanted to use k = dw + w ^ w, using ^ to indicate the wedge product. The second summand is 0 (right?) so we get k = dw = d/dz* (z*/(1+zz*)) dz* ^ dz = -1/(1+zz*)^2 dz* ^ dz. However, this disagrees with both example 9.1 page 3 of http://www.maths.manchester.ac.uk/~tv/Teaching/Differential%20Geometry/2008-2009/lecture9.pdf and https://mathoverflow.net/questions/227233/first-chern-class-of-the-tautological-line-bundle-over-mathbbcpn

What am I doing wrong? Also, if anyone could show how one actually goes about calculating the integral I would appreciate it

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Do your worst!

I'm surprised it hasn't decade.

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.

I said "hey look, an escaPEA"

No one near me but it didn't half make me laugh for a good hour or so!

Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂

It really does, I swear!

They’re on standbi

Pilot on me!!

Nothing, he was gladiator.

Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.

This sub is mostly just NSFW puns now.

If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.

Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.

When I got home, they were still there.

What did 0 say to 8 ?

" Nice Belt "

So What did 3 say to 8 ?

" Hey, you two stop making out "

I won't be doing that today!

This morning, my 4 year old daughter.

Daughter: I'm hungry

Me: nerves building, smile widening

Me: Hi hungry, I'm dad.

She had no idea what was going on but I finally did it.

Thank you all for listening.

There hasn't been a post all year!

Where ever you left it 🤷‍♀️🤭

You take away their little brooms

It was about a weak back.

Why

It’s pronounced “Noel.”

After all his first name is No-vac

What, then, is Chinese rap?

Edit:

Notable mentions from the comments:

• Spanish/Swedish/Swiss/Serbian hits

• French/Finnish art

• Country/Canadian rap

• Chinese/Country/Canadian rock

• Turkish/Tunisian/Taiwanese rap

There hasn't been a single post this year!

(Happy 2022 from New Zealand)

Nothing, it just waved

Him: I can explain everything!

(It's his best joke yet I think)

Bob

So that I could frequently say, "I am going to walk 5 miles now."

Edit: My most popular post on Reddit! 😀 Thank you for the awards.

Just to clarify, 12345678

Me grabbing a soda from my (what I thought was) half full 12pk...

Notices there's only 2;

Me: "Awe man... This is a damn bird box!" Her: "What the hell does that mean?!" Me: (Pulls both cans out & shows them to her) "It's only got Toucans."

I'm not ashamed to admit the look on her face was glorious.

I was just sitting there doing nothing.

But nobody ever mentions his sister, Onya, who invented the starter pistol.
