The Demise of an Old Conjecture: Unraveling the Complexity of Spheres

Mathematicians have disproven the telescope conjecture, which means that the universe of different shapes in high dimensions is more complex than previously thought. The disproof has wide-ranging implications and highlights the importance of homotopy theory in classifying topological spaces and understanding maps between them. Counting maps becomes particularly interesting when the source space has a higher dimension than the target space, and mathematicians aim to determine the number of maps between spaces of any difference in dimension.

Swallowtail Catastrophe Found in Non-Hermitian Systems: Study

Researchers from the Hong Kong University of Science and Technology, Xiangtan University and Southern University of Science and Technology recently unveiled a possible connection between catastrophe theory and non-Hermitian physics. Their paper, published in Nature Physics, specifically shows that a structurally rich degeneracy, known as the swallowtail catastrophe, can naturally exist in non-Hermitian systems. The recent work by this team of researchers establishes a connection between the mathematical catastrophe theory and non-Hermitian physics, two areas of study that were previously perceived as unrelated.
