This workshop aims to foster mutual understanding among researchers working in diverse yet related fields of cosmology. Our primary focus is on the generation of primordial fluctuations during inflation and the subsequent structure formation of the Universe. Several related topics have been discussed in both fields.

The workshop will focus on invited talks, but general talks will also be accepted. This workshop is planned to be held in-person only.

The topics to be covered in this workshop include:

• Effective field theory approach
• Coarse-graining of small scales
• Separate Universe approach
• Stochastic approach and infrared physics in inflation
