Geometric characterization on the solvability of regulator equations [PDF]

open access: yes, 2008
The solvability of the regulator equation for a general nonlinear system is discussed in this paper by using geometric method. The ‘feedback’ part of the regulator equation, that is, the feasible controllers for the regulator equation, is studied ...

On Lp-solvability of stochastic integro-differential equations [PDF]

open access: yes, 2021
In this thesis, we investigate the Lp-solvability of a class of (possibly) degenerate stochastic integro-differential equations (SIDEs) of parabolic type, which includes the Zakai equation in nonlinear filtering for jump diffusions and the Kolmogorov ...

Solvability for Generalized Applications [PDF]

open access: yes, 2022
Solvability is a key notion in the theory of call-by-name lambda-calculus, used in particular to identify meaningful terms. However, adapting this notion to other call-by-name calculi, or extending it to different models of computation - such as call-by ...

Rothe–Legendre pseudospectral method for a semilinear pseudoparabolic equation with nonclassical boundary condition

open access: yesNonlinear Analysis, 2022
A semilinear pseudoparabolic equation with nonlocal integral boundary conditions is studied in the present paper. Using Rothe method, which is based on backward Euler finitedifference schema, we designed a suitable semidiscretization in time to ...

Perturbations of normally solvable nonlinear operators, I

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
Let X and Y be Banach spaces and let ℱ and 𝒢 be Gateaux differentiable mappings from X to Y In this note we study when the operator ℱ+𝒢 is surjective for sufficiently small perturbations 𝒢 of a surjective operator ℱ The methods extend previous results in

On the solvability of Dirichlet problem for the weighted p-Laplacian [PDF]

open access: yesOpuscula Mathematica, 2012
The paper investigates the existence and uniqueness of weak solutions for a non-linear boundary value problem involving the weighted \(p\)-Laplacian. Our approach is based on variational principles and representation properties of the associated spaces.

Existence for Nonlinear Fourth-Order Two-Point Boundary Value Problems

open access: yesDynamics, 2023
The present paper is devoted to the solvability of various two-point boundary value problems for the equation y(4)=f(t,y,y′,y″,y‴), where the nonlinearity f may be defined on a bounded set and is needed to be continuous on a suitable subset of its domain.

Solvability = Typability + Inhabitation [PDF]

open access: yes, 2021
We extend the classical notion of solvability to a lambda-calculus equipped with pattern matching. We prove that solvability can be characterized by means of typability and inhabitation in an intersection type system P based on non-idempotent types.

New criteria for solvability, nilpotency and other properties of finite groups in terms of the order elements or subgroups [PDF]

open access: yesInternational Journal of Group Theory, 2023
In this survey we shall describe some recent criteria for solvability, nilpotency and other properties of finite groups $G$, based either on the orders of the elements of $G$ or on the orders of the subgroups of $G$.
