Bright and Dark Breathers on an Elliptic Wave in the Defocusing mKdV Equation
ABSTRACT Breathers on an elliptic wave background consist of nonlinear superpositions of a soliton and a periodic wave, both traveling with different wave speeds and interacting periodically in the space‐time. For the defocusing modified Korteweg–de Vries equation, the construction of general breathers has been an open problem since the elliptic wave ...

Stable super-resolution limit and smallest singular value of restricted Fourier matrices
Super-resolution refers to the process of recovering the locations and amplitudes of a collection of point sources, represented as a discrete measure, given $M+1$ of its noisy low-frequency Fourier coefficients.

Plank theorems and their applications: A survey
Abstract Plank problems concern the covering of convex bodies by planks in Euclidean space and are related to famous open problems in convex geometry. In this survey, we introduce plank problems and present surprising applications of plank theorems in various areas of mathematics.

We studied the movable singularities of solutions of autonomous non-algebraic first-order ordinary differential equations in the form of y′=I(y(t)) and y′=I1(y(t))+I2(y(t))+⋯+In(y(t)), aiming to prove that all movable singularities of all complex ...

From pathological to paradigmatic: A retrospective on Eremenko and Lyubich's entire functions
Abstract This paper surveys the impact of Eremenko and Lyubich's paper “Examples of entire functions with pathological dynamics”, published in 1987 in the Journal of the London Mathematical Society. Through a clever extension and use of classical approximation theorems, the authors constructed examples exhibiting behaviours previously unseen in ...

VLSI Design of a Variable-Length FFT/IFFT Processor for OFDM-Based Communication Systems
The technique of {orthogonal frequency division multiplexing (OFDM)} is famous for its robustness against frequency-selective fading channel. This technique has been widely used in many wired and wireless communication systems.

In this study, the nonlinear partial differential equation that governs the free vibration of a carbon nanotube composite beam is analytically investigated using the truncated M‐fractional derivative. This model is a beam supported by a nonlinear viscoelastic base and reinforced by carbon nanotubes.

On Stereographic Semicircular Quasi Lindley Distribution
In this paper, we made anattempt to construct a new Semicircular model, we call this as “StereographicSemicircularQuasi Lindleydistribution,” by applying modified inverse Stereographicprojection on Quasi Lindley distribution (Rama and Mishra (2013)) for ...
