Asymptotics of randomly weighted sums without moment conditions of random weights

This paper investigates the asymptotic behaviors of randomly weighted sums with upper tail asymptotically independent increments under new conditions without requiring moment assumptions on the weights, deriving uniform asymptotics and applying them to estimate finite-time ruin probabilities in discrete-time risk models.

Strong monodromy conjecture for defining polynomials of projective hypersurfaces having only weighted homogeneous isolated singularities

This paper proves the strong monodromy conjecture for defining polynomials of projective hypersurfaces with weighted homogeneous isolated singularities in the specific cases where the hypersurface is a reduced curve or has homogeneous singularities in dimension at least four, demonstrating that an "amazing cancellation" prevents potential counterexamples.

Finite Block Length Rate-Distortion Theory for the Bernoulli Source with Hamming Distortion: A Tutorial

This paper provides a self-contained tutorial on finite block length rate-distortion theory for a Bernoulli source with Hamming distortion, deriving the classical rate-distortion function, illustrating its computation via the Blahut-Arimoto algorithm, and analyzing finite-length refinements governed by rate-distortion dispersion with accompanying numerical examples.

The Quintic Wave Equation with Kelvin-Voigt Damping: Strichartz estimates, Well-posedness and Global Stabilization

This paper establishes the global well-posedness and uniform exponential stabilization of the critical quintic wave equation in a 3D bounded domain with locally distributed Kelvin-Voigt damping by combining frequency-space Littlewood-Paley analysis, critical Strichartz estimates, and microlocal defect measures to overcome derivative loss and geometric obstructions.

Optimal Consumption and Portfolio Choice with No-Borrowing Constraint in the Kim-Omberg Model

This paper solves an intertemporal utility maximization problem with a no-borrowing constraint and stochastic excess returns in the Kim-Omberg framework by employing Lagrange duality to transform the primal problem into a dual singular control problem, which is then characterized via an auxiliary two-dimensional optimal stopping problem to derive optimal consumption and portfolio strategies.

Concentration of the largest induced tree size of Gn,pG_{n,p} around the standard expectation threshold

This paper extends the known concentration of the largest induced tree size in random graphs Gn,pG_{n,p} to all vanishing edge probabilities pn1/2ln3/2np \gg n^{-1/2} \ln^{3/2} n and demonstrates that for sparser graphs where n1pn1/2n^{-1} \ll p \ll n^{-1/2}, this size fails to concentrate around the standard expectation threshold.

Predicting Mersenne Prime Exponents Using Euler's Quadratic Polynomial C(n) = n^2 + n + 41 with Nearest-Integer Rounding

This paper proposes the Wright-Euler Mersenne Exponent Hypothesis, which utilizes Euler's quadratic polynomial C(n)=n2+n+41C(n) = n^2 + n + 41 combined with nearest-integer rounding to identify candidate exponents for Mersenne primes, demonstrating a significantly higher accuracy and lower error rate compared to exponential regression models while effectively narrowing the search space for GIMPS testing.
