abstract
In the present paper, we aim to introduce the cohomology of $\mathcal{O}$-operators defined on the Hom-Lie conformal algebra concerning the given representation. To obtain the desired results, we describe three different cochain complexes and discuss the interrelation of their coboundary operators. And show that differential maps on the graded Lie algebra can also be defined by using the Maurer-Cartan element. We further find out that, the $\mathcal{O}$-operator on the given Hom-Lie conformal algebra serves as a Maurer-Cartan element and it leads to acquiring the notion of a differential map in terms of $\mathcal{O}$-operator $\delta_{\mathcal{T}}$. Next, we provide the notion of Hom-pre-Lie conformal algebra, that induces a sub-adjacent Hom-Lie conformal algebra structure. The differential $\delta_{\beta,\alpha}$ of this sub-adjacent Hom-Lie conformal algebra is related to the differential $\delta_{\mathcal{T}}$. Finally, we provide the deformation theory of $\mathcal{O}$-operators on the Hom-Lie conformal algebras as an application to the cohomology theory, where we discuss linear and formal deformations in detail.

Rota-type operators on 2-dimensional dendriform algebras
The claimed classifications of Rota-type operators on 2D dendriform algebras are invalid as stated, with table entries that fail the defining operator equations.

Rota-Type Operators on 2-Dimensional Pre-Lie Algebras
The paper attempts to classify Rota-type operators on all 2-dimensional complex pre-Lie algebras, but the proofs and tables contain errors, including operator matrices that fail their own defining equations.

Central derivations of low-dimensional Zinbiel algebras
The tabulated central derivations for low-dimensional Zinbiel algebras contain entries that violate the paper's own definition, so the classification is unreliable.

An Algorithmic Approach to Inner Derivations of Low-Dimensional Zinbiel Algebras
The central claim that ad_w(u)=u∘w-w∘u is a derivation of every Zinbiel algebra is false; a counterexample appears in the paper's own four-dimensional table.
