A Novel Corpus of Discourse Structure in Humans and Computers
Babak Hemmatian, Sheridan Feucht, Rachel Avram +7
We present a novel corpus of 445 human- and computer-generated documents, comprising about 27,000 clauses, annotated for semantic clause types and coherence relations that allow fo…
Computing Evans functions numerically via boundary-value problems
Blake Barker, Rose Nguyen, Björn Sandstone +2
The Evans function has been used extensively to study spectral stability of travelling-wave solutions in spatially extended partial differential equations. To compute Evans functio…
Toward nonlinear stability of sources via a modified Burgers equation
Margaret Beck, Toan Nguyen, Bjorn Sandstede +1
Coherent structures are solutions to reaction-diffusion systems that are time-periodic in an appropriate moving frame and spatially asymptotic at to spatially periodi…
Perturbations of embedded eigenvalues for the planar bilaplacian
Gianne Derks, Sara Maad Sasane, Bjorn Sandstede
Operators on unbounded domains may acquire eigenvalues that are embedded in the essential spectrum. Determining the fate of these embedded eigenvalues under small perturbations of…
Existence of multi-pulses of the regularized short-pulse and Ostrovsky equations
Vahagn Manukian, Nick Costanzino, Christopher K. R. T. Jones +1
The existence of multi-pulse solutions near orbit-flip bifurcations of a primary single-humped pulse is shown in reversible, conservative, singularly perturbed vector fields. Simil…
