Derivative of Dirac Delta Distribution Hello, I am wondering about the derivative of the Dirac delta distribution ##\delta(t)##. I know: $$\frac{d}{dt} u(t) = \delta(t)$$ So what is ##\frac{d}{dt} \delta(t)##? How do we take the derivative of a distribution? I've heard...

We also show that higher derivative Lagrangians are tachyon-free if the higher derivative terms are given by a function of the field strength but not of a function of the derivatives of the field strength. Finally, we consider the necessity of the boundary term for the higher derivative term...
), where δ is the Dirac delta. If M n is a multiplier of order n and f 1 , . . . , f n are functions on R, we define the quantity Λ n (M n ; f 1 , . . . , f n ) by Λ n (M n ; f 1 , . . . , f n ) := Γn M n (ξ 1 , . . . , ξ ...
