How Long Is the Coast of Quantum Chemistry? Or, How to Evaluate Density Functional Theory as a Scientific Revolution

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
Within quantum chemistry, density functional theory (DFT) is a revolution. This serves as an example of a multitude of other scientific events, supporting the idea that revolutions are always large, if observed with the appropriate magnification. ABSTRACT Distinguishing scientific revolutions from normal science is a subjective, conflicting matter ...

Generalized Logistic Maps in the Complex Plane: Structure, Symmetry, and Escape-Time Dynamics

open access: yesAxioms
In this paper, we introduce a generalised formulation of the logistic map extended to the complex plane and correspondingly redefine the classical Mandelbrot and Julia sets within this broader framework.

The Area of the Mandelbrot Set and Zagier's Conjecture

open access: yesIntegers, 2017
We prove Zagier's conjecture regarding the 2-adic valuation of the coefficients $\{b_m\}$ that appear in Ewing and Schober's series formula for the area of the Mandelbrot set in the case where $m\equiv 2 \mod 4$.

Generalized Scaling of Blue Metabolism in River Basins

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract River networks play a central role in regulating biogeochemical transformations at the catchment scale, yet a general scaling theory linking network structure to integrated metabolic function is still lacking. By positing the fundamental differences between blue (fluvial) and green (terrestrial) metabolisms in river basins, we focus on the ...

Non-linearity of the dynamics of transcendental function using Fibonacci–Mann iteration and some critical remarks

open access: yesAlexandria Engineering Journal
With a generalized setting of transcendental functions associated with a non-linear variable, we have observed the combinatorial structures of the fractals of Julia sets and Mandelbrot sets due to the function zκcos(zκ)+pz2+q, in the complex plane with p,

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 7, Page 1355-1385, July 2026.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

When integers embrace the beauty of complex numbers [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика

Newton-Mandelbrot set and Murase-Mandelbrot set

open access: yes
We obtain four extended Newton's methods and three extended Mandelbrot's recurrence formulas from the Wasan (Japanese mathematics in the Edo period (1603-1868)). Furthermore, two extended Newton's methods relate to one of the extended Mandelbrot's recurrence formulas. We lead four types of extended Mandelbrot recurrence formulas.

Parameter-Driven Analysis of Complex Fractals via Picard–Abbas Iteration

open access: yesFractal and Fractional
Fractal geometry has recently been advanced through fixed-point iteration schemes, enabling new analytical approaches. In this paper, we apply the Picard–Abbas iteration process to study Mandelbrot sets, Julia sets, and biomorphs for polynomials of the ...
