The Riemann problem in gasdynamics
Electronic Journal of Differential Equations, 2009 In this note we give a proof of the existence of a solution to the Riemann problem in one-dimensional gasdynamics. Lax's 1957 paper on conservation laws leaves no doubt that such a solution exists, but it seems to us that there may be interest in a ...

JCPP Advances, EarlyView.Abstract Background Understanding symptom patterns of emerging psychopathology is essential for early detection and intervention. Network analysis offers a promising approach by conceptualizing emerging psychopathology as dynamic interactions between symptoms over time.

Advances in Difference Equations, 2019 The exact solutions of the Riemann problem for a symmetric system of Keyfitz–Kranzer type are obtained in fully explicit forms. Furthermore, the global solutions of the double Riemann problems are also constructed explicitly when the initial data are ...

On the Riemann Problem for a Combustion Model [PDF]
SIAM Journal on Mathematical Analysis, 1993 Summary: This paper studies the Riemann problem for a combustion model and proves that the solution exists globally and the solution converges uniformly, away from the shock, to a travelling wave solution as \(t\to +\infty\). The results are obtained by using the method of characteristics, a maximum principle and that of the equation is a nonlinear ...

JEADV Clinical Practice, EarlyView.ABSTRACT Background Residual limb hyperhidrosis (RLH) is a frequent and debilitating condition among lower‐limb prosthetic users. Although aluminium chloride is recommended first‐line for focal hyperhidrosis, its efficacy in RLH has not previously been evaluated in prospective studies.

Analysis of the Stability of the Riemann Problem for a Simplified Model in Magnetogasdynamics
Advances in Mathematical Physics, 2016 The generalized Riemann problem for a simplified model of one-dimensional ideal gas in magnetogasdynamics in a neighborhood of the origin (t>0) in the (x,t) plane is considered.

Hearing the Serre Invariant of a Compact p‐Adic Analytic Manifold
Mathematische Nachrichten, EarlyView.ABSTRACT Using a previous novel way of defining kernel functions for Laplacian integral operators on a compact p$p$‐adic analytic manifold X$X$, one such operator Δ0s$\Delta _0^s$ with s∈R$s\in \mathbb {R}$ is applied to hearing the Serre invariant i(X)$i(X)$ by showing that a wavelet eigenvalue (with the wavelet having small support) is always ...

Mathematical Methods in the Applied Sciences, EarlyView.A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Generalized Riemann problem for a totally degenerate hyperbolic system
Electronic Journal of Differential Equations, 2018 We consider the generalized Riemann problem for the Suliciu relaxation system in Lagrangian coordinates and we calculate the first-order expansion given by LeFloch and Raviart to verify our results, then we show the explicit solution for the ...
