A Non-relativistic Logarithmic Conformal Field Theory from a Holographic Point of View [PDF]
, 2011 We study a fourth-order derivative scalar field configuration in a fixed Lifshitz background. Using an auxiliary field we rewrite the equations of motion as two coupled second order equations.

A Second Derivative SQP Method: Global Convergence [PDF]
SIAM Journal on Optimization, 2010 Sequential quadratic programming (SQP) methods form a class of highly efficient algorithms for solving nonlinearly constrained optimization problems. Although second derivative information may often be calculated, there is little practical theory that justifies exact-Hessian SQP methods.

Zeros of Bessel function derivatives
, 2016 We prove that for $\nu>n-1$ all zeros of the $n$th derivative of Bessel function of the first kind $J_{\nu}$ are real and simple. Moreover, we show that the positive zeros of the $n$th and $(n+1)$th derivative of Bessel function of the first kind $J_{\nu}
