      We study the evolution of curves with fixed length and clamped boundary conditions moving by the negative L2L^2L2-gradient flow of the elastic energy. For any initial curve lying merely in the energy space we show existence and parabolic smoo...

      Ranking sectors and countries within global value chains is of paramount importance to estimate risks and forecast growth in large economies. However, this task is often non-trivial due to the lack of complete and accurate information on th...

      Buffon's Problem determines Gaussian Curvature in three Geometries

      Probability
      A version of the classical Buffon problem in the plane naturally extends to the setting of any Riemannian surface with constant Gaussian curvature. The Buffon probability determines a Buffon deficit. The relationship between Gaussian curvat...

      Conservation efforts in green security domains to protect wildlife and forests are constrained by the limited availability of defenders (i.e., patrollers), who must patrol vast areas to protect from attackers (e.g., poachers or illegal logg...

      We establish an equivalence between two approaches to quantization of irreducible symmetric spaces of compact type within the framework of quasi-coactions, one based on the Enriquez-Etingof cyclotomic Knizhnik-Zamolodchikov (KZ) equations a...

      Spectrum scarcity necessitates innovative, spectral-efficient strategies to meet the ever-growing demand for high data rates. Faster-than-Nyquist (FTN) signaling emerges as a compelling spectral-efficient transmission method that pushes tra...

      The log minimal model program for K\"ahler 333-folds

      In this article we show that the Log Minimal Model Program for Q\mathbb{Q}Q-factorial dlt pairs (X,B)(X, B)(X,B) on a compact K\"ahler 333-fold holds. More specifically, we show that after finitely many divisorial contractions and flips we obtain e...

      We study finite non-linearizable subgroups of the plane Cremona group which potentially could be stably linearizable....

      Several new product identities in relation to two-variable Rogers-Ramanujan type sums and mock theta functions

      September 12, 2020

      Mathematics
      Combinatorics
      Product identities in two variables x,qx, qx,q expand infinite products as infinite sums, which are linear combinations of theta functions; famous examples include Jacobi's triple product identity, Watson's quintuple identity, and Hirschhorn's ...
