where i is the imaginary unit and L is the interaction Lagrangian, written in terms of quantum fields depending on the spacetime coordinates X. The T symbol means time-ordered. For the terminology used in this page, see for instance chapters IV and V, "The Scattering Matrix" and "The Feyn...
What is the meaning of ε in the epsilon-delta definition of limits? The symbol ε, also known as epsilon, represents the margin of error or the tolerance level in the definition of a limit. It is a small positive number that allows us to determine how close the function values must be...
The modulus symbol (absolute value) of the quantity is used just to stress on the fact that we do not know whether the error is negative, 0, or positive. Since the exact quantity Q is never known, we take Q as the quantity of (sufficiently) higher order accuracy and Q′ as the ...
It is well known that electromagnetic radiation from radiating elements (e.g., antennas, apertures, etc.) shows dependence on the element’s geometry shape in terms of operating frequencies. This basic principle is ubiquitous in the design of radiators i

where 𝛿̂𝑙𝑙′δ^ll′ is the Kronecker symbol. These reflectances and transmittances correspond to the spectral peaks in the form of Lorentz contours with the full width at half maximum: 2𝛾=∑𝑙=1𝑁1𝜏𝑙.2γ=∑l=1N1τl. (8) For one channel, we have 𝑙=𝑙′l...
results in two new pasts also equivalent to each other for length-L−1future morphs: (15) Since this must be true foranyjoint symbol, we replace (a,b) with(X,Y)0in Eq. (15), giving: (16) To arrive at our result, we need to multiply the left side of Eq. (16) by ...
