We revisit the correspondence between three-dimensional gauged linear sigma models and K-theoretic Gromov-Witten theory. We show that the K-theoretic Hori-Vafa formula for the grassmannian arises from the three-dimensional gauge theory upon including an appropriate anomaly-cancellation factor. Furthermore, we derive K-theoretic I-functions for isotropic grassmannians by incorporating symmetric and anti-symmetric tensor representation fields together with suitable boundary conditions.

1. Introduction A DC link capacitor (DCLC) uses metallized films (MFs) with self-healing properties as a dielectric [1,2]. DCLCs have advantages in terms of withstanding high-temperature and their voltage, large ripple current, and lifespan [3,4]. DCLCs play a role in voltage equalization, energy storage and filtering in converters [5]. Currently, DCLCs are widely used in power transmission, clean energy and electric locomotives [6,7].

1 Introduction Sodium ion batteries are considered as the next generation electrochemical devices for large-scale energy storage because of low cost, abundant resources, environmental friendliness, and high safety.[1-5] The performance of the cathode materials plays a key role in realizing a stable and high-efficiency energy storage.
