Daniel Brosch

Postdoc at Klagenfurt University! Love anything that has symmetries, the more the better.

Our @MSCActions doctoral network TENORS is about to start: 15 PhD positions - 2 at @UiTNorgesarktis. Please share and point motivated master students who are interested in taking a PhD in mathematics to https://t.co/rCH9DHete3

A very nice conference on "Symmetry, Stability, and interactions with Computation" at the Centre International de Rencontres Mathématiques https://t.co/WIeVsdBYXf .
Thanks to Tromsø Forskningsstiftelse for supporting this beautiful event at this amazing place.

A strong representation of SDPs at #SIAMOP23 from @alpenadriauni this week! Melanie Siebenhofer attacked the edge expansion, Diane Puges introduced bounds for the cutwidth, Jan Schwiddessen presents a new MaxCut solver, and I talked about new tools for Sidorenko's conjecture.

[LucasVB (1ucasvb) @LucasVB]

Also, I had a stupid error in the symmetry trajectory code. I fixed it. Here's an update with fancy coloring.

It's far more sensitive now. Those tiny pockets of symmetry are very real and very cool to explore.

"Synonym"? Oh you mean a word isomorphism

[Daniel Brosch @DanBrosch]

@SophieHuiberts reveal.js of course, not .jl (but I would love a julia version...)

[Daniel Brosch @DanBrosch]

@SophieHuiberts I can recommend reveal.jl! LaTeX support, and you can embed videos (or even interactive plots) as it's web-based.

[Daniel Brosch @DanBrosch]

@matbesancon I love my remarkable 2! Mostly use it for note taking, occasionally for presenting (then making use of community hacks for better screen sharing options).

[CWI @CWInl]

Four world-leading experts, Amir Ali Ahmadi, Etienne De Klerk, Rekha Thomas & @fvallentin will speak at CWI Lectures on Algebraic and Geometric Methods in #Optimization. We will celebrate Monique Laurent’s appointment as a CWI Fellow. Please register via https://t.co/QqvXQAvCpN

[POEMA @POEMA_H2020]

Thank you all for taking the time out of your busy schedules to attend @POEMA_H2020 Final #workshop at @Sorbonne_Univ_ . Your presence made this event a great success. The #tutorials of the workshop will be available on our website https://t.co/oCdoU6jbtv

[Aleksandr Kazachkov @akazachk]

Please join @lyeskhalil and me for another #DOTs season of virtual #DiscreteOptTalks, starting Fri, Sep 23, 2022 at 1pm ET. Visit https://t.co/6XwNBoA4p0 for talk details and subscribe to our mailing list at https://t.co/KfrxxUOFKd to receive updates. Hope to see you soon! #orms

[Daniel Brosch @DanBrosch]

Greg Blekherman starting off the final @POEMA_H2020 workshop talking about decidability of graph homomorphism inequalities and flag sums-of-squares

[Daniel Brosch @DanBrosch]

Today is the last day of @iccopt2022 in Betlehem, one of the first big optimization conferences since Covid! In the last parallel session @kirschner_felix gave a fantastic talk on computing polynomial approximation kernels using SDPs.

[Alex Kontorovich @AlexKontorovich]

Andrei Okounkov has posted to arxiv four *lovely* popular accounts of the work of this year's Fields medalists:

👀 Sneak a peek at the deepest & sharpest infrared image of the early universe ever taken — all in a day’s work for the Webb telescope. (Literally, capturing it took less than a day!) This is Webb’s first image released as we begin to #UnfoldTheUniverse: https://t.co/tlougFWg8B

[Daniel Brosch @DanBrosch]

@SandMouth Do you have an example?

[Quanta Magazine @QuantaMagazine]

@jordanacep @EricaKlarreich BREAKING: Maryna Viazovska, a Ukrainian number theorist, has been awarded the Fields Medal, math’s highest honor. She is the second woman to receive the medal in its 86-year history. @7homaslin and @EricaKlarreich report:

Get excited, the Summer of Math Exposition #2 is on!

https://t.co/bzznBE8Pbr

As part of it, we've set up a space to help coordinate collaborations between domain experts (profs, teachers, etc) and content creators (animators, developers, artists, etc).

Daniel Brosch, Sven Polak: New lower bounds on crossing numbers of $K_{m,n}$ from permutation modules and semidefinite programming https://t.co/4Ukc91tAOH https://t.co/vEuagmkYmk

[Daniel Brosch @DanBrosch]

We exploit the symmetries of the semidefinite programming bound by de Klerk, Maharry, @dimpase, Richter and Salazar using a novel decomposition method, and introduce a new, slightly worse, but more efficient bound. The preprint is available at https://t.co/If3CWT6pFm .

[Daniel Brosch @DanBrosch]

Today @SCPolak presented our new preprint "New lower bounds on crossing numbers of K(m,n)" at Norcom at @UiTNorgesarktis in Tromsø!
