Non-uniqueness for the ab family of equations in periodic case

Rajan Puri

For the cubic ab-family of equations with $a \neq = 0$ , it is proved that there exists an initial data in the Sobolev space $H^{s}$ , $s < 3/2$ , with non-unique solutions on the circle.

Beta Critical for the Schrodinger Operator with Delta Potential

Rajan Puri

For the one dimensional Schrödinger operator in the case of Dirichlet boundary condition, we show that $β_{cr}$ is positive and zero for the case of Neumann and Robin boundary cond…

Non-uniqueness for the ab-family of equations

John Holmes, Rajan Puri

We study the cubic ab-family of equations, which includes both the Fokas-Olver-Rosenau-Qiao (FORQ) and the Novikov (NE) equations. For $a \neq = 0$ , it is proved that there exist initi…
