Epsilon-delta proofs define a limit to lie within an interval as small as possible, thereby guaranteeing that the function stays close to the undefined point, even though the point is never reached by the function. Why do we need the epsilon-delta definition of a limit?
Homework Statement Hi there, I'm stuck at a problem where I have (sorry i don't know how to use mathtype so I'll try my best at making this clear) the integral of a dirac delta function squared: int[delta(x*-x)^2] between minus infinity and infinity (x*=constant) I know that...
Forum:General Math L Covariant and Contravariant Kronecker Delta operating on Tensor I am aware that the following operation: mathbf{M}_{ij} \delta_{ij} produces mathbf{M}_{ii} or mathbf{M}_jj However, if we have the following operation: mathbf{M}_{ij} \delta^i{}_j will the tensor...
There has been significant work recently on integer programs (IPs)min{c⊤x:Ax≤b,x∈Zn}with a constraint marixAwith bounded subdeterminants. This is motivated by a well-known conjecture claiming that, for any constantΔ∈Z>0,Δ-modular IPs are efficiently solvable, which are IPs where the...
