Zero-curvature representation for a new fifth-order integrable system

A Lax Operator Hierarchy for the New Fifth Order Integrable System

We consider the Lax representation of the new two-component coupled integrable system recently discovered by the author. Connection of the hierarchy of infinitely many Lax pairs with each other is presented.

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...

Integrability of the Bakirov System: A Zero-Curvature Representation

On the property of for a second-order system with zero diagonal coefficient

Abstract: This paper investigates the problem of whether all trajectories of the system and cross the vertical isocline, which is very important for the existence of periodic solutions and oscillation theory. Sufficient conditions are given for all trajectories to cross the vertical isocline.  

Scalar second order evolution equations possessing an irreducible sl2-valued zero curvature representation by

We find all scalar second order evolution equations possessing an sl2-valued zero curvature representation that is not reducible to a proper subalgebra of sl2. None of these zero-curvature representations admits a parameter. For more than twenty years, researchers are being attracted by the problem of classification of nonlinear systems possessing a zero-curvature representation (ZCR). Efforts ...
