Impact of Pulsar SAX J1748.9-2021 Observations on $f(\mathcal{Q}, \mathbb{T})$ Gravity
The main objective of this study is to investigate the viability and stability of a pulsar filled with anisotropic matter in $f(\mathcal{Q}, \mathbb{T})$ gravity, where $\mathcal{Q}$ represents non-metricity and $\mathbb{T}$ is the trace of the energy-momentum tensor. In this context, we employ non-singular solution and a particular model of this gravity. We use junction conditions to evaluate unknown constants in the metric coefficients. Observations from the pulsar SAX J1748.9-2021 star are e…

👋 Hello! I’m Łukasz. Thirty-something, living in Warsaw, Poland. On fedi since 2021 or so. Right now, I'm merging my two accounts into one and giving this profile a fresh new start.
I live a few parallel lives.
Most of the time I’m a web developer. I work with TypeScript, React and all that jazz. But I still enjoy static site generators and good ol’ HTML/CSS.
In another life, I’m a documentary photographer and photojournalist. I’m interested in activism, art and culture, politics, and pretty much anything interesting happening on city streets. A big part of my photography journey involves documenting protests and demonstrations in Poland, especially those related to human rights and social issues. I’m also drawn to street art, particularly when it carries strong messages.
I occasionally blog and translate. Many years ago I wrote two books about WordPress. However, these days I’m more likely to go outside and touch grass than spend even more time in front of a screen.
Outside of that, expect me to post about mental health and politics. I promise to use CWs when appropriate.
I post in both English and Polish, depending on the topic.
Aaaand that’s it. Nice to meet you! ☺️

Moment-SOS hierarchies for arrow-type polynomial matrix inequalities with applications to structural optimization
The Arrow Decomposition (AD) technique, initially introduced in [Mathematical Programming 190(1-2) (2021), pp 105-134], demonstrated superior scalability over the classical chordal decomposition in the context of Linear Matrix Inequalities (LMIs) if the matrix in question satisfied suitable assumptions. The primary objective of this paper is to extend the AD method to address Polynomial Optimization Problems (POPs) involving large-scale Polynomial Matrix Inequalities (PMIs), with the solution f…

A note on Wang's conjecture for harmonic functions with nonlinear boundary condition

A note on Wang's conjecture for harmonic functions with nonlinear boundary condition
We obtain some Liouville type theorems for positive harmonic functions on compact Riemannian manifolds with nonnegative Ricci curvature and strictly convex boundary and partially verifies Wang's conjecture (J. Geom. Anal. 31 (2021)). For the specific manifold $\mathbb{B}^n$, we present a new proof of this conjecture, which has been resolved by Gu-Li (Math. Ann. 391 (2025)). Our proof is based on a general principle of applying the P-function method to such uniqueness results. As a further app…

A Data-Driven Model Predictive Controller to manage epidemics: The case of SARS-CoV-2 in Mauritius
This work investigates the benefits of implementing a systematic approach to social isolation policies during epidemics. We develop a mixed integer data-driven model predictive control (MPC) scheme based on an SIHRD model which is identified from available data. The case of the spread of the SARS-CoV-2 virus (also known as COVID-19) in Mauritius is used as a reference point with data obtained during the period December 2021 to May 2022. The isolation scheme is designed with the control decision…

My colleague Sri Muppidi broke the news Wednesday of OpenAI’s latest fundraising talks as it seeks to raise an unprecedented $40 billion. One previously unreported detail is that SoftBank bought about $240 million in shares from a small group of current and former employees this spring.That deal ...

EBCDIC is incompatible with GDPR
Welcome to acronym city! The Court of Appeal of Brussels has made an interesting ruling. A customer complained that their bank was spelling the customer's name incorrectly. The bank didn't have support for diacritical marks. Things like á, è, ô, ü, ç etc. Those accents are common in many languages. So it was a little surprising that the bank didn't support them. The bank refused to spell their c…

Tankrabatt: Wie wir uns zu Tode subventionieren
Die Verbrennung fossiler Brennstoffe richtet massive Schäden an. Dennoch wird sie gefördert – etwa durch den Tankrabatt. Dabei gäbe es sinnvolle Alternativen, von denen auch Geringverdiener profitieren.

🇵🇱 Cześć! Jestem Łukasz. Trójka z przodu. Warszawa. Na fedi mniej-więcej od 2021 r. Łączę dwa konta w jedno i od tej pory będzie tu więcej polskojęzycznych postów (a jeśli obserwowałxś mnie na polskojęzycznym koncie, to dostaniesz więcej treści po angielsku 😄).
Mam kilka równoległych żyć.
Przez większość czasu buduję rzeczy w internetach, głównie z użyciem TypeScriptu, Reacta i całej reszty tego jazzu. Ciągle jednak lubię generatory stron statycznych i stary dobry HTML/CSS.
W innym życiu jestem fotografem-dokumentalistą i fotoreporterem. Interesuje mnie aktywizm, sztuka, kultura, polityka oraz wszystko, co jest ciekawe, a dzieje się na ulicach miast. Dużo uwagi poświęcam protestom i demonstracjom w Polsce, zwłaszcza dotyczącym praw człowieka i kwestii społecznych. Interesuje mnie też sztuka uliczna, zwłaszcza taka, która niesie ze sobą mocne komunikaty.
Zdarza mi się blogować i tłumaczyć teksty. Wiele lat temu napisałem dwie książki o WordPressie. Obecnie jednak wolę gdzieś wyjść niż spędzać jeszcze więcej czasu przed ekranem.
Okazjonalnie zdarza mi się postować o zdrowiu psychicznym i polityce. Staram się używać CW kiedy to możliwe.
Postuję po polsku i angielsku w zależności od tematu.
No i... chyba tyle. Miło Cię widzieć!

Global Bifurcation of Spiral Wave Solutions to the Complex Ginzburg-Landau Equation
We use the $\mathbb T^2$-equivariant degree to establish the existence of unbounded branches of rotating spiral wave solutions with any number of arms for the complex Ginzburg Landau equation GLe on the planar unit disc, leveraging the spatial symmetries inherent to the problem and avoiding limiting constraints encountered in previous studies (Dai 2021) that utilized the classical Leray-Schauder degree. Our results provide rigorous mathematical justification for the formation and persistence of…
