An illustration of formal moduli problems with differential graded Lie algebras
This article provides an exposition to the topic of formal moduli problems, emphasizing its connections with differential graded Lie algebras, and mainly following from Jacob Lurie's DAG X: Formal Moduli Problems. As such, this paper should not be viewed as a presentation of original work, but rather a concise introduction to the subject in the form of a set of organized notes. I hoped to make this paper feel welcoming and insightful for the non-expert enjoyer of derived algebraic geometry, lik…

Filings: Bengaluru-based fintech Cred, which offers rewards for paying credit card bills and more, raised ~$72M at a $3.5B valuation, down from $6.4B in 2022 (The Economic Times)

Cred raises fresh funds from GIC, others; valuation cut by 45% to $3.5 billion
The fintech major was valued at $6.4 billion in 2022 during its last major fund infusion. The current fund infusion is in the form of primary capital, which means that existing investors have not sold any shares in this round. The drop in valuation was in line with the company's plans to list in India over the next two years, people in the know said.

Explicit construction of benign subgroup for Higman's reversing operation
For the Higman reversing operation $ρ$ and for a set of integer-valued functions $\mathcal X$ the following has been proved. Let the subgroup $A_{\mathcal X}$ be benign in the free group $F$, let the respective finitely presented overgroup $K_{\mathcal X}$ with its finitely generated subgroup $L_{\mathcal X}$ be given for $A_{\mathcal X}$ explicitly, and let the set $\mathcal Y = ρ\mathcal X$ be obtained from $\mathcal X$ by the reversing operation $ρ$. Then $A_{\mathcal Y}$ also is benign i…

Conditional a priori error estimates of finite volume and Runge-Kutta discontinuous Galerkin methods with abstract limiting for hyperbolic systems of conservation laws in 1D
We derive conditional a priori error estimates of a wide class of finite volume and Runge-Kutta discontinuous Galerkin methods with abstract limiting for hyperbolic systems of conservation laws in 1D via the verification of weak consistency and entropy stability, as recently proposed by Bressan et al.~\cite{BressanChiriShen21}. Convergence in $L^\infty L^1$ with rate $h^{1/3}$ is obtained under a time step restriction $τ\leq ch$, provided the following conditions hold: the exact solution is pi…

I've been working on a full calendar app upgrade to the Discordian date widget I made years ago for Android. It's nearly ready for release, just got a bug or three to fix first.
