Abstract
The paper discusses the regularity of continuous-time fuzzy martingales. The necessary and sufficient conditions that a continuous-time fuzzy submartingale has a right-continuous adapted modification are given. In particular, any continuous-time fuzzy martingale has a right-continuous adapted modification. The results are a generalization of the counterpart results of classical martingale theory and the proof is completely different. The principal technique is based on the key theorem by Y. Feng (1999) which states that the convergence of fuzzy numbers in uniform metric is transformed into the pointwise convergence of the corresponding support functions
