Notice how I inserted capitalization and punctuation in your question. Sigma is not being neglected, it is just zero for sinusoidal waveforms. The substitution is NOT made for nonsinusoidal functions. You did not mention that. Any good book on Laplace transforms will show you why substitution of jw in a Laplace expression gives the phasor representation of that function.While solving problems in Laplace transforms, we usually substitute s=jω. But actually s=σ+jω. Why are we neglecting σ here?
What is its significance?
