Fractal and Fractional, 2021 Fractional-order boundary value problems are used to model certain phenomena in chemistry, physics, biology, and engineering. However, some of these models do not meet the existence and uniqueness required in the mainstream of mathematical processes ...

Uniqueness and Existence Results
, 2022 AbstractIn this chapter, we establish Theorems 10.1007/978-3-030-95088-0_1#FPar4 and 10.1007/978-3-030-95088-0_1#FPar5 and show that, under the assumptions of these theorems, the sequence $$n\mapsto f^p_n[g]$$ n ↦ f

An existence and uniqueness theorem for the dynamics of flexural shells
Mathematics and mechanics of solids, 2020 In this paper, we define, a priori, a natural two-dimensional model for a time-dependent flexural shell. As expected, this model takes the form of a set of hyperbolic variational equations posed over the space of admissible linearized inextensional ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Abstract and Applied Analysis, 2013 We discuss the existence and uniqueness of solution for two types of fractional order ordinary and delay differential equations. Fixed point theorems are the main tool used here to establish the existence and uniqueness results.

Generating and Adding Flows on Locally Complete Metric Spaces
, 2012 As a generalization of a vector field on a manifold, the notion of an arc field on a locally complete metric space was introduced in \cite{BC}. In that paper, the authors proved an analogue of the Cauchy-Lipschitz Theorem i.e they showed the existence ...

Codes and designs—existence and uniqueness
Discrete Mathematics, 1991 This is a well written general survey concerning the usefulness of coding theory in proving existence and uniqueness results in design theory. The scope of the paper is limited, dealing significantly with only two examples. The coding theory aspects of the work of C. Lam, et. al. on the non-existence of a projective plane of order 10 is outlined.
