What process links several certificates together to establish trust between all the certificates involved?

I believe the answer is  certificate chaining
 certificate chaining refers to the process of verification that rely on the usage of more than one authorization.
This process is widely used in corporations to protect the company against potential data theft.

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
