Researcher develops new tool for understanding hard computational problems that appear intractableThe notion that some computational problems in math and computer science can be hard should come as no surprise. There is, in fact, an entire class of problems deemed impossible to solve algorithmically. Just below this class lie slightly "easier" problems that are less well-understood—and may be impossible, too.

This is the important conclusion of Giuseppe Mussardo, professor of Theoretical Physics at SISSA, and Andrè Leclair of Cornell University reported in an article just published in the Journal of Statistical Mechanics (JSTAT). The two scientists have shown that not only one can arrive at the solution to one of the most famous problems in mathematics, the Riemann conjecture, but that it is the physics of chaotic motions and the probability laws that regulate them that provide the elegant key to understand this great mathematical enigma. The research behind the article just published, lasted three years and the final part of it, the authors said, was "a real tour de force in the data analysis of an incredibly large set of prime numbers, the basic constituents of arithmetic, i.e. the real atoms of mathematics."

Mathematics Tue, 23 Nov 2021 12:49:15 ESTnews556894146An exploration of tipping in complex systemsComplex systems can be found in a diverse array of real-world scenarios, but are unified by their ability to suddenly transition between drastically different patterns of behavior. Known as 'tipping,' this type of transformation is generally triggered by small changes in the parameters of individual systems—whose effects can rapidly cascade to alter entire networks of interacting subsystems. In this special issue, EPJST explores the nature of tipping in complex systems through 21 new articles. Together, the studies reveal recent trends and directions of research within the field, and highlight the pressing challenges it will face in the future.

Although the contamination of one such lake, Lake Onuma on Mount Akagi, was measured for a few years after the accident, its long-term contamination has been uncertain. Now, a research team from Japan has shed light on this issue.

Inspired by the map-coloring problem, it asks: Given a network of nodes connected by links, what's the minimum number of colors you need to color each node so that no links connect two of the same color? For small numbers of colors and links, looking for a solution is straightforward: Just try all possible combinations. But as links increase, the problem becomes more constrained—until, if there are too many links and not enough colors, no solution may exist at all.

Applicable to datasets with millions of organizations, it runs faster and delivers more accurate results than competing approaches. By unwinding the complex web of owners, the algorithm makes it possible to get an idea of a closed company's compliance with environmental, social, and governance standards by looking at the practices of its more transparent owner.
