Vopěnkova Alternativní teorie množin v matematickém kánonu 20. století

Filosofický časopis, 2022
Vopěnka’s Alternative Set Theory can be viewed both as an evolution and as a revolution: it is based on his previous experience with nonstandard universes, inspired by Skolem’s construction of a nonstandard model of arithmetic, and its inception has been

Nonstandard second-order arithmetic and Riemann's mapping theorem [PDF]

, 2013
In this paper, we introduce systems of nonstandard second-order arithmetic which are conservative extensions of systems of second-order arithmetic. Within these systems, we do reverse mathematics for nonstandard analysis, and we can import techniques of ...

Impact of Nonstandard Default Risk of the Urban Investment and Development Companies on the Urban Investment Bond Market

Systems, 2023
Under the general trend of reducing leverage and strictly controlling new implicit debts of local governments, the risk of nonstandard defaults by urban investment and development companies (UIDCs) continues to be released, which will increase the credit

An operator equation and relativistic alterations in the time for radioactive decay

International Journal of Mathematics and Mathematical Sciences, 1996
In this paper, using concepts from the nonstandard physical world, the linear effect line element is derived. Previously, this line element was employed to obtain, with the exception of radioactive decay, all of the experimentally verified special theory
