Structural rule A famous structural rule is known as cut. Considerable effort is spent by proof theorists in showing that cut rules are superfluous in various logics. More precisely, what is shown is that cut is only (in a sense) a tool for abbreviating proofs, and does not add to the theorems that can be proved. The successful 'removal' of cut rules, known as "cut elimination", is directly related to the philosophy of "computation as normalization" (see Curry–Howard correspondence); it often gives a good indication of the complexity of deciding a given logic. Structural rule In proof theory, a structural rule is
Funeral Rule that the funeral home purchases from a third-party vendor on behalf of their customer. Some examples of cash advance items include: - Flowers - obituary notice - Pallbearers - Officiating clergy - Organist or soloist The Funeral Rule stresses the importance of the consumer to clarify with the funeral home whether there is a premium charged for cash advance items. Some funeral homes pass through the exact expense to their customers, while others apply a mark-up, which is allowable under The Funeral Rule. According to The Funeral Rule, funeral homes that charge a mark-up must disclose this in writing to
