Interpreting Extended Set Theory in Classical Set Theory
نویسنده
چکیده
We exhibit an interpretation of the Extended Set Theory proposed by Dave Childs in classical Zermelo-Fraenkel set theory with the axiom of choice and an axiom asserting the existence of arbitrarily large inaccessible cardinals. In particular, if the existence of arbitrarily large inaccessible cardinals is consistent with ZFC, then Childs’s Extended Set Theory is also consistent.

ON THE FUZZY SET THEORY AND AGGREGATION FUNCTIONS: HISTORY AND SOME RECENT ADVANCES
Several fuzzy connectives, including those proposed by Lotfi Zadeh, can be seen as linear extensions of the Boolean connectives from the scale ${0,1}$ into the scale $[0,1]$. We discuss these extensions, in particular, we focus on the dualities arising from the Boolean dualities. These dualities allow to transfer the results from some particular class of extended Boolean functions, e.g., from c...
متن کاملHydrogen Abstraction Reaction of Hydroxyl Radical with 1,1-Dibromoethane and 1,2-Dibromoethane Studied by Using Semi-Classical Transition State Theory
The hydrogen abstraction reaction by OH radical from CH2BrCH2Br (R1) and CH₃CHBr2 (R2) is investigated theoretically by semi-classical transition state theory. The stationary points for both reactions are located by using ωB97X-D and KMLYP density functional methods along with cc-pVTZ basis. Single-point energy calculations are performed at the QCISD(T) and CCSD(T) levels of theory with differe...
متن کاملAn extended hesitant group decision-making technique based on the prospect theory for emergency situations
Throughout the present manuscript, we are going to introduce a novel group emergency decision-making technique in which the application of prospect theory explains the psychological behaviour of the decision maker who is affected by the hesitancy and uncertainty of cognition in decision making problems.\Instead of usual aggregation procedure, we implement here a new fusion technique that ...
متن کاملTopological structure on generalized approximation space related to n-arry relation
Classical structure of rough set theory was first formulated by Z. Pawlak in [6]. The foundation of its object classification is an equivalence binary relation and equivalence classes. The upper and lower approximation operations are two core notions in rough set theory. They can also be seenas a closure operator and an interior operator of the topology induced by an equivalence relation on a u...

We review the conformal symmetry group and investigate the isomorphism between the conformal group and O( D,2 ) . We study the classically conformal invariant scalar theory in D -dimensions with a non-positive potential . We solve the equations of motion by assigning O(D-1, 2)symmetry to the classical solutions with broken translational symmetry in all directions. Then we consider a six d...
