What is zero input and zero state in Laplace?
The zero input solution is the response of the system to the initial conditions, with the input set to zero. The zero state solution is the response of the system to the input, with initial conditions set to zero. The complete response is simply the sum of the zero input and zero state response.

What part of math is Laplace?
The zero state, then, is a state of unknowable and seemingly infinite potential, from where everything (i.e. our futures, our ideas, our choices) can emerge. It is a state of total possibility — a blank canvas that functions as a conduit towards creation or, maybe in more technically accurate terms, [re]formation.
Is Laplace inverse unique?
In electrical circuit theory, the zero state response (ZSR) is the behaviour or response of a circuit with initial state of zero. The ZSR results only from the external inputs or driving functions of the circuit and not from the initial state.

In summary, a zero initial condition in linear systems refers to the starting state of a system where all initial inputs, outputs, and internal states are equal to zero. Understanding this condition is important for analyzing and predicting system behavior.

Technically, a point z0 is a pole of a function f if it is a zero of the function 1/f and 1/f is holomorphic (i.e. complex differentiable) in some neighbourhood of z0. A function f is meromorphic in an open set U if for every point z of U there is a neighborhood of z in which at least one of f and 1/f is holomorphic.
What is a pole and zero in Z transform?
No, for a function to have a Laplace transform it is necessary for the integral which defines a Laplace transform to exist. The integral does not exist for f(x) = 1/x because of the singularity at x =0. The integral does not exist for f(x) = exp(x^2) because the function grows too quickly as x becomes large.
What is pole-zero of a function?

The values of z for which H(z) = 0 are called the zeros of H(z), and the values of z for which H(z) is ¥ are referred to as the poles of H(z). In other words, the zeros are the roots of the numerator polynomial and the poles of H(z) for finite values of z are the roots of the denominator polynomial.
