Abstract

fetched live from OpenAlex

In thispaper, we study a singular 𝑝⁡(𝑥)-Laplacian equation that incorporates both variable singular and superlinear nonlinearities. By applying Ekeland’s variational principle and a constrained minimization approach, we establish the existence and uniqueness of a positive solution when the variable singularity β⁡(𝑥) is within the interval (1,∞). As an application of our results, we provide two examples from the basic problem in the boundary layer theory of these pseudoplastic fluids with the no-slip boundary condition at both plates.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
