On gelation for the Smoluchowski coagulation equation

Comptes Rendus. Mathématique
Motivated by the recent results of Andreis–Iyer–Magnanini [2], we provide a short proof, revisiting the one of Escobedo–Mischler–Perthame [7], that for a large class of coagulation kernels, any weak solution to the Smoluchowski equation loses mass in ...

Seeley-DeWitt coefficients in N $$ \mathcal{N} $$ = 2 Einstein-Maxwell supergravity theory and logarithmic corrections to N $$ \mathcal{N} $$ = 2 extremal black hole entropy

Journal of High Energy Physics, 2019
We investigate the heat kernel method for one-loop effective action following the Seeley-DeWitt expansion technique of heat kernel with Seeley-DeWitt coefficients.

How Competitive Is Myanmar's Rice Sector? A Comparison of Production Costs and Efficiency

Agribusiness, EarlyView.
ABSTRACT This paper analyzes the cost competitiveness of rice production in Myanmar by examining production costs, cost efficiency, and the potential effect of improving cost efficiency on the country's global competitiveness. To achieve this, we conduct a comparative analysis of production costs among major rice‐producing countries and estimate the ...

Assessing the sensitivity of energy-energy correlations in e + e − annihilation to TMD dynamics

Journal of High Energy Physics
We critically examine the back-to-back limit of the energy-energy correlation (EEC) in e + e − annihilation as a potential source of information on the Collins-Soper kernel and the strong coupling constant.

Logarithmic terms in discrete heat kernel expansions in the quadrant

Annales de l’Institut Henri Poincaré D, Combinatorics, Physics and their Interactions
In the context of lattice walk enumeration in cones, we consider the number of walks in the quarter plane with fixed starting and ending points, prescribed step-set, and given length. After renormalisation, this number may be interpreted as a discrete heat kernel in the quadrant.

Efficiency and Technology Gap in European Apple Production—A Metafrontier Model for Germany, Italy, and Poland

Agribusiness, EarlyView.
ABSTRACT EU member states have exhibited varying rates of apple production growth. Technical efficiency (TE) estimation is suitable for identifying best‐practice farm performance. This study examined whether the development of the apple sector in Germany, Italy, and Poland was influenced by production efficiency, access to technology, as well as ...

Quasilinearization-Collocation Method for the Numerical Solution of Nonlinear Fractional Volterra Integro-Differential Equations With Logarithmic Weakly Singular Kernel

International Journal of Mathematics and Mathematical Sciences
In this paper, we use quasilinearization technique, product integration rule, and collocation method to present a new numerical method to solve nonlinear fractional Volterra integro-differential equations with logarithmic weakly singular kernel.

Product quasi-interpolation in logarithmically singular integral equations

Mathematical Modelling and Analysis, 2012
A discrete high order method is constructed and justified for a class of Fredholm integral equations of the second kind with kernels that may have boundary and logarithmic diagonal singularities.

Ambient metric construction of Q-curvature in conformal and CR geometries

, 2003
We give a geometric derivation of Branson's Q-curvature in terms of the ambient metric associated with conformal structures; it naturally follows from the ambient metric construction of conformally invariant operators and can be applied to a large class ...
