BLOCKCHAIN IMPLEMENTATION AND PRINCIPAL-AGENT THEORY [PDF]

open access: yesBusiness Excellence and Management, 2023
One of the biggest issues in organization in centuries is problem raised by the relationship between actor inside. This problem called principal-agent problem which explained by principal agent theory (PAT).

Morita theory for Hopf algebroids, principal bibundles, and weak equivalences [PDF]

open access: yes, 2017
We show that two flat commutative Hopf algebroids are Morita equivalent if and only if they are weakly equivalent and if and only if there exists a principal bibundle connecting them.

Difference Equations: Disconjugacy, Principal Solutions, Green's Functions, Complete Monotonicity [PDF]

open access: yesTransactions of the American Mathematical Society, 1978
We find analogues of known results onnth order linear differential equations fornth order linear difference equations. These include the concept of disconjugacy, Pólya’s criterion for disconjugacy, Frobenius factorizations, generalized Sturm theorems, existence and properties of principal solutions, signs of Green’s functions, and completely monotone ...

Practical solutions for complex variable function for radius of tunnel plastic zone under non-hydrostatic pressures and their application extension

open access: yesYantu gongcheng xuebao, 2023
In order to address the non-circular plastic boundary of rock circular tunnels under non-hydrostatic pressures, a simple complex variable function for the stress in an elastic zone is firstly introduced by using the analogy method.

Polyaxial strength criterion and closed-form solution for squeezing rock conditions

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2020
In this paper, a nonlinear strength criterion is proposed using the average of intermediate (σ2) and minor (σ3) principal stresses in place of σ3 in Ramamurthy (1994)'s strength criterion.

Singular measure as principal eigenfunction of some nonlocal operators

open access: yes, 2013
In this paper, we are interested in the spectral properties of the generalised principal eigenvalue of some nonlocal operator. That is, we look for the existence of some particular solution $(\lambda,\phi)$ of a nonlocal operator. $$\int_{\O}K(x,y)\phi(y)

Principal solutions of positive linear Hamiltonian systems [PDF]

open access: yesJournal of the Australian Mathematical Society, 1976
AbstractThe Hamiltonian system Y′ = BY + CZ, Z′ = – AY – B*Z is considered where the coefficients are continuous on I = [a, ∞, C = C* ≧ 0, and A = A* ≦ 0. A solution (Y, Z) satisfying Y*Z = Z*Y is defined to be principal (coprincipal) provided that (i) Y−1 exists on I (Z−1 exists on I) and (ii) as t→∞ ( as t → ∞).

Antiprincipal solutions at infinity for symplectic systems on time scales

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
In this paper we introduce a new concept of antiprincipal solutions at infinity for symplectic systems on time scales. This concept complements the earlier notion of principal solutions at infinity for these systems by the second author and Šepitka ...
