|Existence, philosophy, logic: the fact that there is something to which properties can be attributed. That does not mean that something has to be given immediately or can be perceived by the senses. See also ontology, properties, predicates, existence statements, realism, quantification, ascription._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments.|

Existence/consistency/concept/Hilbert: If one assigns features to a concept which contradict themself, so I say: the concept does not exist mathematically.
FregeVsHilbert/(s): would say the concept can exist, but there is no object for it.
Existence/number/Hilbert: the existence of a concept is proved if it can be shown that there are never contradictions in the application of a finite number of logical conclusions.
This would prove the existence of a number or a function.
Real numbers/existence/axioms/Hilbert: here the consistency is a proof for the axioms and it is also the proof for the existence of the continuum._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution.
