A Model for the Outbreak of COVID-19: Vaccine Effectiveness in a Case Study of Italy,uals. We compute the basic reproductive ratio of the model and study the local and global stability for it. We solve the model numerically based on the case of Italy. We propose a vaccination model, and we derive threshold conditions for preventing infection spread in the case of imperfect vaccines.

Random Tempered Distributions on Locally Compact Separable Abelian Groups,empered generalized functions—of Schwartz type—on a locally compact abelian separable group, and we characterize the set of those generalized functions that have a mean. We show that this approach covers both the case of the torus and the real line case and also allows us to define tempered random d

Stochastic Methods in Investigation of Modern Networks,s, and with its help, we can get the best solution of optimization (Bander and White, Transport Sci 36(2):218–230, 2002; Bertsekas, Dynamic programming and optimal control. Athena Scientific, Belmont, 1995). In the current article, we use Kolmogorov equation to find out the optimal parameters of the

Double-Barrier Option Pricing Under the Hyper-Exponential Jump Diffusion Model,istic function is rational (hyper-exponential jump diffusion (HEJD) case). In a standard way, this problem is reduced to a convolution equation on a finite interval, which is solved explicitly using the modified Wiener–Hopf method. On the basis of the obtained explicit formulas, an algorithm for cal

Single Jump Filtrations: Preservation of the Local Martingale Property with Respect to the Filtratiy mentioned by Herdegen and Herrmann (2016) that . is also a local martingale with respect to the filtration . that it generates if . is the smallest .-field with respect to which . is measurable. We provide an example of a local martingale with respect to a general single jump filtration which is n

Random Harmonic Processes with New Properties,d series (SHCS). The sufficient conditions for both the wide-sense stationary property and the mean ergodic property for random harmonic (trigonometric) processes are set. Moreover, we describe a class of wide-sense stationary and mean ergodic random harmonic processes function with nonuniformly ran
