Exploring Alternative Cosmologies with the LSST: Simulated Forecasts and Current Observational Constraints

Autor: Kumar, Dharmendra, Mitra, Ayan, Adil, Shahnawaz A., Sen, Anjan A.

In recent years, the Lambda Cold Dark Matter (LCDM) model, which has been pivotal in cosmological studies, has faced significant challenges due to emerging observational and theoretical inconsistencies. This paper explores alternative cosmological mo

BMO estimates for Hodge-Maxwell systems with discontinuous anisotropic coefficients

Autor: Kumar, Dharmendra, Sil, Swarnendu

We prove up to the boundary $\mathrm{BMO}$ estimates for linear Maxwell-Hodge type systems for $\mathbb{R}^{N}$-valued differential $k$-forms $u$ in $n$ dimensions \begin{align*} \left\lbrace \begin{aligned} d^\ast \left( A(x) du \right) &= f &&\text

Carleman estimates for sub-Laplacians on Carnot groups

Autor: Arya, Vedansh, Kumar, Dharmendra

In this note, we establish a new Carleman estimate with singular weights for the sub-Laplacian on a Carnot group $\mathbb G$ for functions satisfying the discrepancy assumption in (2.16) below. We use such an estimate to derive a sharp vanishing orde
