Multiscale Methods for Wave Propagation in Materials with Sign-Changing Coefficients

Abstract. From a mathematical perspective, the extraordinary properties of metamaterials are often reflected in the coefficients of the governing partial differential equations. These coefficients may fall outside the assumptions of classical theory, particularly when the effecti...

Properties and Proximal Point Type Methods for Strongly Quasiconvex Functions in Hilbert Spaces

We study strongly quasiconvex functions defined on Hilbert spaces and taking extended real values from both theoretical and algorithmic points of view. To this end, we verify the existence of (global) minimizers and the properties of the proximal operator for such functions, prev...

CELLServe: An SLO-Aware and Cost Efficient LLMs Serving System for Serverless Computing Environments

Large Language Models (LLMs) have enabled diverse AI applications. However, LLMs inference impose unprecedented computational and memory overhead, creating an inherent trade-off between latency Service Level Objectives (SLOs) and resource constraints. Serverless computing, with o...
