Majorization bounds for distribution functions
Statistics & Probability Letters, 2012 Let $X$ be a random variable with distribution function $F,$ and $X_{1},X_{2},...,X_{n}$ are independent copies of $X.$ Consider the order statistics $X_{i:n},$ $i=1,2,...,n$ and denote $F_{i:n}(x)=P\{X_{i:n}\leq x\}.$ Using majorization theory we write upper and lower bounds for $F$ expressed in terms of mixtures of distribution functions of order ...

Brownian Motion With Partial Resetting Conditioned to Stay Positive
Bulletin of the London Mathematical Society, Volume 58, Issue 3, March 2026.Abstract We consider Brownian motion with partial resetting, which has recently attracted a lot of attention in physics as well as the mathematics literature. We analyze the speed of convergence of this process towards stationarity as well as its quasistationary behavior.

Existence of Time-Scale Class of Three Dimensional Fractional Differential Equations
International Journal of Analysis and Applications, 2019 The holomorphic results for fractional differential operator formals have been established. The analytic continuation of these outcomes has been studied for the fractional differential formalwhere U is the open unit disk. The benefit of such a problem is

On a rigidity property for quadratic gauss sums
Mathematika, Volume 72, Issue 1, January 2026.Abstract Let N$N$ be a large prime and let c>1/4$c > 1/4$. We prove that if f$f$ is a ±1$\pm 1$‐valued multiplicative function, such that the exponential sums Sf(a):=∑1⩽n

Temperature majorant cross sections in Monte Carlo neutron tracking
, 2015 This paper discusses the generation of temperature majorant cross sections, the type of cross sections required by two separate techniques related to Monte Carlo neutron tracking, namely, the Dopplerbroadening rejection correction (DBRC) and target ...

Optimal stopping with nonlinear expectation: geometric and algorithmic solutions [PDF]
, 2023 We use the geometry of functions associated with martingales under nonlinear expectations to solve risk-sensitive Markovian optimal stopping problems. Generalising the linear case due to Dynkin and Yushkievich (1969), the value function is the majorant ...

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.We first establish a general positivity principle for functions whose logarithms possess Dirichlet‐series expansions with nonnegative coefficients. If log Z(x) = ∑n≥2cnn−x, cn ≥ 0, then, for r, s > 0, the shifted cross‐ratio Qr,s(x) = (Z(x)Z(x + r + s))/(Z(x + r)Z(x + s)) has a positive logarithmic Dirichlet expansion, a positive discrete Laplace ...

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.In this paper, a complete Lie symmetry analysis of the time‐fractional Benjamin–Bona–Mahony (BBM) equation in the Riemann–Liouville sense is presented. We give a full symmetry classification and two infinitesimal generators Q1 and Q2, unlike previous studies concerned with the construction of particular solutions.
