Self Hosting is not the answer.
"I realized how privileged I am to have the skills required for digital sovereignty. I realized how unattainable, unsustainable, and unrealistic self-hosting is as a mass solution to the problems we face. I realized that self-reliance isn't freedom — it's the luxury of retreating from a system that others can't escape."

GSO Defects: IIA/IIB Walls and the Surprisingly Stable $\mathrm{R}7$-Brane
The recently proposed Swampland Cobordism Conjecture predicts the existence of new non-supersymmetric objects which supplement the spectrum of low-energy gravitational effective field theories. In this paper, we study a subset of these defects related to the GSO projection on the string worldsheet. These include the predicted domain wall between Type IIA and IIB superstring theories and the newly-discovered $\mathrm{R}7$-brane. We study these defects in two different ways: via long-string probe…

Not all knots are smoothly round handle slice
Freedman and Krushkal showed that if the surgery conjecture and the $s$-cobordism conjecture hold for all topological 4-manifolds, then every link with pairwise zero linking numbers is topologically round handle slice. Kim, Powell, and Teichner showed that every knot is topologically round handle slice. We show that infinitely many knots fail to be smoothly round handle slice.

On homology spheres of the trivial local equivalence class

On homology spheres of the trivial local equivalence class
In the homology cobordism group $Θ_{\mathbb{Z}}^3$, it is not known if there is a non-trivial linear dependence between Seifert fibered spheres. Based on involutive Heegaard Floer theory, Hendricks, Manolescu, and Zemke introduced the local equivalence group $\mathfrak{I}$ with the homomorphism $h:Θ_{\mathbb{Z}}^3 \rightarrow \mathfrak{I}$. And it is possible to find a non-trivial linear dependence between the image of Seifert fibered spheres in $\mathfrak{I}$ using the work of Dai and Stoffr…

A note on the Thom morphism for the classifying space of certain Lie groups and gauge groups
We give a complete description of which non-torsion generators are not in the image of the Thom morphism from complex cobordism to integral cohomology for the classifying space of exceptional Lie groups except for E_8. We then show that the Thom morphism is not surjective for the classifying space of the gauge group of a principal E_7-bundle over the four-dimensional sphere. We use the results to detect nontrivial elements in the kernel of the reduced Thom morphism for Lie groups and their clas…

A note on the involutive invariants of splices
A natural family of potentially 2-torsion elements in the integer homology cobordism group consists of splices of knots with their mirrors. We show that such 3-manifolds have locally trivial involutive Floer homology. We show some related families of splices also have locally trivial involutive Floer homology. Our arguments show that many gauge theoretic invariants also vanish on these 3-manifolds.
