Existence and Uniqueness [PDF]
Thermodynamics of Materials with Memory, 2011 The study of differential problems related to materials with fading memory began with the work of Graffi [111, 112]. Later on, these studies were considered by many authors, and in particular, a new important description of such phenomena was given by Dafermos in [47, 46], using semigroup theory, where besides existence and uniqueness of the solution ...

Existence and uniqueness of Bowen-York Trumpets [PDF]
Classical and Quantum Gravity, 2011 We prove the existence of initial data sets which possess an asymptotically flat and an asymptotically cylindrical end. Such geometries are known as trumpets in the community of numerical relativists.Comment: This corresponds to the published version in ...

A new class of double phase variable exponent problems: Existence and uniqueness [PDF]
Journal of Differential Equations, 2021 In this paper we introduce a new class of quasilinear elliptic equations driven by the so-called double phase operator with variable exponents. We prove certain properties of the corresponding Musielak-Orlicz Sobolev spaces (an equivalent norm, uniform ...

Existence and uniqueness of maximal solutions to SPDEs with applications to viscous fluid equations [PDF]
Stochastics and Partial Differential Equations: Analysis and Computations, 2022 We present two criteria for the existence and uniqueness of a maximal strong solution for a general class of stochastic partial differential equations. Each criterion has its corresponding set of assumptions and can be applied to viscous fluid equations ...
